必ずしも2要素認証(2FA)を設定する必要はありませんが、あなたのアカウントを保護する命綱として設定することを推奨します。

2番目の要素の登録

"設定" -> "ログイン"({settingLoginMail})で 2番目の要素に接続することができます。管理者として設定する際は、"設定"-> "ユーザー管理" ({settingUsersMail})でユーザーの2要素認証を設定することができます。

Tutanotaは現在以下の2番目の要素をサポートしています。

• Yubikeyなどのセキュリティキー（U2F）。U2Fは現在ChromeとOperaでサポートされています。
• Google AuthenticatorやAuthyなどの認証用アプリのTOTP
• 私たちは現在より多くの二番目の要素のサポートを計画しています。もしご希望があればソーシャルメディアから私たちにお知らせください！

管理者と“ノーマル”ユーザーが2番目の要素の設定ができますが、削除することができるのは管理者のみです。

注意：もし、二番目の要素を失くしてしまった場合、あなたはアカウントにログインすることができなくなります。これを防ぐために複数の二番目の要素を登録できます。加えて、二番目の要素を追加したときに表示されるリカバリーコードを控えておくことで再ログインすることができます。

• 二番目の要素での認証 *
  ログインする時に二番目の要素の一つで認証する必要があります。または他のログイン中のクライアントからセッションを受け入れることも可能です。もし登録した二番目の要素をあなたのブラウザがサポートしていない場合、別のクライアントからのセッションだけを受け入れることだけができます。

• • 二番目の要素を失くした場合のリセットの方法

リカバリーコードを書き留めている場合は、二番目の要素をリセットすることができます。"設定"-> "ログイン" を表示してリカバリーコードを表示させたり、更新することができます。({settingLoginMail})

二番目の要素を失くした場合、ログインページで"その他"-> "アカウントへのアクセスを失くした" ({recoverLink})をクリックしてください 。すべてのセカンドファクターを削除するには、あなたのリカバリーコードとパスワードを入力する必要があります。

When you create a new account, please make sure that:

• You write your password down and keep it somewhere safe.
• You write down your recovery code to never lose access to your Tutanota account.

When it is already too late and you can't login to Tutanota, please make sure that:

• You have entered your email address with the correct ending, e.g. ".de" or ".com".
• The caps lock key is disabled.
• The time on your TOTP device is synchronized correctly (only applies if second factor authentication with TOTP fails).

We do not know your password and can't modify your second factors. However, there are different ways on how to regain access to your mailbox in case of a lost password or second factor.

Administrator is available

If you are a member of an organization or a business: Ask your administrator to reset your password. Each administrator can reset the passwords of other users and admins. If you want to make sure to never lose your Premium account, it's best to have at least two administrators.

Recovery code is available

Your recovery code is your personal code to resetting your account. If you did write it down when you created your account, you can reset your password or second factor using your personal recovery code by clicking on More > Lost account access on the login page.

You can view and also update your recovery code in Settings > Login. You can also find more information on this innovative reset feature on our blog.

You can access all functions of Tutanota via the navigation menu.

• To the left of the navigation menu there is a search field. Here you can search your encrypted mailbox. As all data on the Tutanota servers is encrypted, a search index has to be created that is stored encrypted on your device. Find more details on how our innovative search feature for encrypted data works. Shortcut for search: Click F. Simply enter your search query into the search field. When you are searching your mails, you can click on any offered search result. This will take you to a more detailed search mask. You can define the time from - to, the field, and the folders that should be searched.
  Please note: You can only search emails and contacts, thus, the search field is not shown when you are browsing the 'Settings' of your mailbox.
• Click the three lines to the right to see all menu options. The menu items 'Emails', 'Contacts', 'Settings', and 'Premium' are explained further down.
• If you click on 'Invite' a pre-written mail in Tutanota opens, which you may use to invite your friends to join Tutanota. Please do so! :)
• If you click on 'Community', our website opens here in another tab and you can check out how you can get involved and support our open source project.
• If you click on 'Logout', you log out. Please note: If you have previously saved the password, you are now logged out, but the password is still saved in your browser. To 'unsave' the password, please log out. The login screen appears, click on 'More' and 'Delete credentials'.

To search your encrypted mailbox, simply click on the top search field or press Ctrl+F.

When you press enter, Tutanota takes you to a more detailed search mask. The free search feature goes back one month into the past.

The detailed search mask lets you specify the time frame which should be searched (one month for free users). The unlimited search feature also lets you filter your search, e.g. who sent the email, to whom did you send the email, was the search query contained in the subject or in the body, what folder should be searched.

As all data in Tutanota is encrypted, using our innovative search feature causes a lot of traffic. This is why unlimited search is only available to paying users. Learn here how you can benefit by going Premium for only €1 per month.

If you own one or more domain names that you want to use with Tutanota, you can add these domains to your Tutanota Premium or Pro account. Afterwards you can add email aliases and additional user accounts for your family or company with this domain.

To use your own domain, a Tutanota Premium account is required. You can upgrade your existing, free Tutanota account by clicking on "Premium" in the top menu. If you don't have a Tutanota account, you can register here.

After upgrading you are the admin of your Tutanota Premium account. An additional input field will appear under 'Settings' -> 'Global settings' -> 'Custom email domain' where you need to enter your domain. Activate it by confirming the activation button.

This activation process is only successful if you have configured your MX and SPF records for your domain correctly. The MX record is necessary to relay emails for your domain to the Tutanota servers. The SPF record marks the Tutanota server as valid sender of emails from your domain. You need to configure the following DNS records in the settings of your domain name provider:

MX mail.tutanota.de
TXT v=spf1 include:spf.tutanota.de -all

Depending on your domain hoster, it could also look like this:
HOST NAME:
@ mail.tutanota.de
HOST NAME IP ADDRESS / URL RECORD TYPE
@ v=spf1 include:spf.tutanota.de -all TXT Record

Please note that changes to your DNS records are not immediately available, but can take a few hours to become active. You can check your DNS settings here.

After you have successfully activated your domain, you can add an email alias or create a user under 'Settings' -> 'User management'.

What do I do if activation fails?

Please verify your DNS SOA entry if the activation of your custom domain still fails. We use the SOA entry for detecting your main DNS server. Therefore, the SOA entry must point to a valid name server.

1. Register a Tutanota Premium account here . This will be your initial administrator account. Once you have added additional accounts to your initial administrator account, you can mark all - or just some - as admin accounts. Your administrator account(s) can configure all general settings and manage user accounts, e.g. reset user passwords. As we at Tutanota can not reset passwords, we recommend to have at least two admin accounts. This way you can reset each others password in case you lose one.
2. Add your domain in "Settings" -> "Global settings" -> "Custom email domain". There you will also find instructions on how to configure your MX DNS entries first in order to route incoming SMTP emails to the Tutanota email servers.
3. Add user accounts (i.e. mailboxes) for your domain in "Settings" -> "User management". If you have a large number of users, you can import a CSV file containing user name, email address and optionally the user password. This is useful to automatically create all user accounts in one step.
4. Provide the user passwords to the users, so they can log in into their mailboxes.

Email encryption is needed whenever you want to send a confidential email. That is whenever your emails contains personal information that should not become public. The following examples show the differences between end-to-end encrypted, confidential emails and emails that are not being end-to-end encrypted in Tutanota.

Alice is registered with Tutanota, Bob may be registered with Tutanota or an external recipient and Carol is not registered with Tutanota. In any case all emails (including attachments) are stored encrypted on the Tutanota servers. Independent of the end-to-end encryption, the transport between client and Tutanota servers is secured with SSL and DANE to maximize security.

Sending and receiving end-to-end encrypted emails
The email is encrypted on Alice' client, stored encrypted on the server and can only be decrypted by Alice or Bob.

Sending non-confidential emails
The email is sent via SMTP to the recipient. Still, the sent email is encrypted for Alice on the server and then stored.

Receiving non-confidential emails
When the SMTP email is received by the Tutanota server, it is encrypted for Alice and then stored on the server.

You can change the default sender here in your Settings→ 'Default sender'. This makes your alias the default sender, the Tutanota address will still remain the main account address (name in tab) which can't be changed.
• External recipients of an end-to-end encrypted email receive a notification mail from your Tutanota email address. You can choose the language of this notification email by clicking on the pen symbol on the right (in this screenshot: English is chosen).

Go here in your Settings. You can choose whether emails to external recipients should be encrypted by default ('Confidential') or if you need to click on the lock symbol when composing an email to encrypt it ('Not confidential' = unencrypted by default). Emails to other Tutanota users are always encrypted by default.

暗号化されたメールを外部の受信者に送信する場合は、メールを作成するときにパスワードを指定する必要があります。

一度設定すると、パスワードは自動的にあなたの Tutanota アドレス帳の連絡先に保存されます。次回その受信者にメールを書くときに、メールアドレスを指定するだけで、Tutanota は自動的にパスワードを入力します。パスワードは、2番目のチャネルを介して交換する必要があります。

外部受信者

• Tutanota へのリンクを含む通知メールを受信します (ブラウザが開きます)、
• 交換したパスワードを入力し、
• 自動的に解読された電子メールを読むことができ、内密に返信したり、すべての交換メッセージをエクスポートし、ローカルに保存することができます。

注: 通知メール内のリンクには、パスワードとともに復号化に必要なソルトが含まれています。したがって、暗号化されたメッセージを傍受ししようとする人は、正確なリンクとパスワードを必要とします。(古いリンクは、同じメールアドレスに新しいメールを送信するとすぐに非アクティブになります。

メールボックスに移動する →「メールエイリアス」：」メールエリアスを表示」をクリック。エリアスを追加するにはプラス記号をクリックします。エイリアスのドメインを選択するには、3つのドットボタンをクリックします。これは、Tutanota アカウントに追加した Tutanota ドメインまたは独自のドメインのいずれかになります。

• • 注意してください**: Tutanota ドメインのエイリアスは無効にすることしかできず、削除できません。無効化されたエイリアスは、今後再びアクティブ化する場合に備えて、アカウントにリンクしたままにしておく必要があります。Tutanota で独自のドメインを使用している場合は、自分のドメインでエイリアスを削除して、新しく作成することができます。

デフォルトの送信元アドレスを、自分のドメインエイリアス (またはその他のエイリアス) に変更するには、デフォルトの送信者 このメールボックス →「デフォルトの送信者」を変更します。これにより、エイリアスがデフォルトの送信者になります。ただし、Tutanota アカウントのメインアドレス (タブ内の名前) は変更されません。

Spam detection in Tutanota is multi staged. For incoming unencrypted SMTP emails the received email is checked against DNS blacklists first. In a second stage we filter emails by executing content checks and mark emails as spam or not. Emails that have been marked as spam will be moved to the spam folder of your mailbox. In a third stage we filter spam on the base of user defined email sender lists. This list provides the possibility to classify email addresses as spam (blacklist) or explicit not as spam (whitelist). The check is active for all incoming emails and can be configured by the administrator. The rules are valid for all users.

As administrator for a Tutanota account you can configure the email address list here in Settings. You assign email addresses or domains to one of the following spam rules:

• No spam - Emails from this sender email address are always stored in the inbox.
• Always spam - Emails from this sender email address will always be stored in the spam folder.
• Discard - Emails from this sender email address will be silently discarded. The sender does not get any information about it.

The "No spam" rule has a higher priority than "Always spam" and "Discard" has the lowest priority. Furthermore you are able to define rules based on a domain instead of a single email address. Rules defined for a domain have a lower priority than rules for an email address.

Rules for domains are restricted. You are not able to assign the rules "Always spam" and "Discard" to Tutanota domains, neither to your custom domains.

• Each time you send a mail to a new email address, this address is automatically saved to 'Contacts'. This can be changed here → 'Create contacts'.
• Select a contact and you will get the option to edit (pen symbol to the right) or delete (trash symbol to the right) this contact. You can also send an email to this contact by clicking on the mail button next to the contact's email address.
• You can add new contacts by clicking on the plus symbol in the down right corner. When you create a contact, you can enter all necessary information (see screenshot below).
• The three dot button next to 'All contacts' allows you to import or export contacts via vCard and to merge contacts automatically.
• You can also merge contacts manually: Press Ctrl while selecting two contacts that should be merged. At the top right two buttons appear: 'Delete' and 'Merge'. Click 'Merge' to merge the selected contacts.
• Contacts are sorted alphabetically according to their email address.
• Your entire address book is encrypted, thus, no one can access your contact database stored in Tutanota.

• Click on the pen symbol to activate whitelabel (€2 per user/per month). When you order the whitelabel feature, you can activate the Tutanota login at your own domain (a subdomain), change the look of Tutanota according to your needs (e.g. Corporate Identity) and create secure contact forms for your clients.

• 'Whitelabel domain': Click the pen symbol to activate the whitelabel feature for your own domain. A pop-up shows up where you have to enter the following information (shown in the screenshot):

• Choose a subdomain of your own domain, at which you would like to reach the Tutanota login. This must be a subdomain, a main domain is technically not allowed. Set the CNAME DNS entry for that domain to point to login.tutanota.com. Keep in mind that the DNS changes may take a while until propagated.
  • Upload your domain's SSL certificate chain and
  • your domain's private key to enable the Tutanota login at your domain. Both must be provided in PEM format (base64 coded).
  • 'Custom logo': Click the pen symbol to upload your logo. It will be shown in the top left corner (38x280 pixel) when you load Tutanota at your own domain.

• 'Custom colors': Click the pen symbol to set the colors according to your own corporate design. If you don't set a color, the default color from the Tutanota style sheet will be taken.
• 'Custom meta tags': Click the pen symbol to enter a meta tag.
• Now you can open your custom domain in your browser and see the Tutanota login with your own logo and own colors.

When you order the whitelabel upgrade for your Premium account you can activate the Tutanota login on your own domain (a sub-domain), change the look of Tutanota according to your needs (e.g. corporate identity) and create contact forms for your clients. If you send confidential messages to external recipients, those recipients are also directed to your whitelabel domain.

Complete list of possible customizations:

• Set custom logo (displayed on your whitelabel domain instead of the Tutanota logo).
• Set custom colors (displayed on your whitelabel domain).
• Set custom meta tags for the Tutanota app on your whitelabel domain, like title and social media texts.
• Set a custom imprint link (displayed in the "More" menu on the login page of your whitelabel domain instead of the Tutanota imprint link).
• Set a custom notification email text for external recipients (coming soon).

Preconditions for applying the whitelabel feature:

• You need your custom whitelabel domain. This must be a subdomain. A main domain is technically not allowed. It is also not allowed to add an email domain as whitelabel domain.
• You need a valid SSL certificate for your whitelabel domain and you need to make sure to update it in Tutanota before it expires.

This is how you can setup your whitelabel domain:

1. Choose a subdomain of your own domain, at which you would like to reach the Tutanota login.
2. Set the CNAME DNS entry for that domain to point to login.tutanota.com. Keep in mind that the DNS changes may take a while until propagated.

3. Enable the Tutanota login at your domain by uploading your domain's SSL certificate chain and private key here in your Tutanota Settings - Whitelabel. Both must be provided in PEM format (base64 coded). The private key file content must start with the line "-----BEGIN RSA PRIVATE KEY-----" or "-----BEGIN PRIVATE KEY-----". The certificate file content must start with the line "-----BEGIN CERTIFICATE-----". In order to create a certificate chain from individual certificates create a file in a text editor. Then first copy your domain's certificate into that file and below that certificate any intermediate certificate or certificate bundle that was provided to you in addition to you certificate file. Your certificate chain file might then look like this:

   -----BEGIN CERTIFICATE-----
   (Your SSL certificate, e.g. from your_domain_name.crt)
   -----END CERTIFICATE-----
   -----BEGIN CERTIFICATE-----
   (Your intermediate SSL certificate, e.g. from intermediate.crt)
   -----END CERTIFICATE-----

4. Optionally upload your custom logo to be shown when you load Tutanota at your own domain.

5. Optionally configure your custom colors to be used in Tutanota when you load Tutanota at your own domain.

Now you should be able to open your custom domain in your browser and see the Tutanota login with your own logo and own colors. Additionally you may now order and setup contact forms ("Settings" -> "Contact forms") which allows you to be contacted confidentially.

Please note that your whitelabel customizations will not be visible in the mobile apps.

Contact forms allow you to be contacted confidentially as all messages are automatically end-to-end encrypted.

Create a new contact form

• Click the plus symbol in the down right corner. A pop-up shows up which lets you create a new contact form.

• 'Receiving mailbox': Click the user symbol (left) to select one user who should receive all emails sent via the contact form.
• 'Responsible Persons': If you do not enter anything here, contact requests can be passed on to all users on your domain by the receiving mailbox.
• 'Path': Enter a path to the link where your contact form should be displayed.
• 'Language': Click the three-dot symbol to add another language to your contact form (i.e. French, German, Spanish). Visitors of your website will automatically see the language defined in their browser settings. Once you have added another language, a cross symbol appears so that you can delete any language you do not need anymore.
• 'Page title': Enter a title for your contact form to be displayed on the website. A page title needs to be entered for all added languages.
• 'Header', 'Footer', 'Help page': You can enter three different text fields either in rich text format or as HTML source code. You can switch between rich text and HTML by clicking on the pen symbol to the right. The entered text will be displayed on the contact form on your website.

Manage existing contact forms

• Click the contact form you want to manage.
• Click the pen symbol to the right to edit this form. The pop-up shown above opens. You can manage all fields described under 'Create a local admin group'.
• Click the copy symbol to copy this form. A new contact form pops up where you can change all required fields shown under 'Create a local admin group'. At least the 'Path' and the 'Receiving mailbox' must be changed as the new form must have its own web link and its own recipient.
• Click the delete symbol to delete this contact form.
• Click the Export button further down to export a CSV log of all contact form requests in a given period of time.

• The global admin can create a local admin group to add as well as manage administrators of users and contact forms. Please refer to 'Create a local admin group' for details.
• The user who creates another user or contact form becomes the administrator of the created entity. More precisely, the admin group in which the user is member will become the admin of the entity. If the user is a global admin, then the entity is administrated by the global admins. If the user is a local admin (i.e. member of a local admin group), then that local admin group becomes the admin.
• The global admin can change the administrator of a user by selecting a local admin group under 'Administrated by'.
• Local administrators only see those users and contact forms that they administrate.
• Even if an entity is administrated by a local admin group, the global admins can still administrate the entity.
• A contact form is always administrated by the administrator of its receiving mailbox. So if a global admin changes the receiving mailbox of a contact form, the admin of this user mailbox becomes the administrator of the contact form.

• Click on 'Upgrade' to upgrade your free Tutanota account to Premium or Pro. Look at the screenshot below to view the upgrading process.

Once upgraded you can add 'Extensions':

• Please note: When you want to downgrade back to the free version, you have to disable all these extensions as they are only available to paying Tutanota users. This means, for example, that all your aliases must be deactivated. They will still be linked to your account so that you can reactivate them when you upgrade again at a later stage.

• 'Contact forms': After adding whitelabel, you can also add a contact form to your website. This allows visitors of your website to directly get in touch with you via Tutanota's end-to-end encrypted contact form.
• 'Delete Account': Here you can delete the account. Your email address and aliases will be deleted and can't be reactivated. If you want to use your Tutanota email addresses in another account, it is important to enter the 'Take over email address' here. Then you can add the deleted email addresses to the stated Tutanota take over email account.
• Downgrade back to Free: You can unsubscribe from Premium here. Next to 'Subscription', click the pen icon and select the Free plan.
