귀하의 Tutanota 암호

Tutanota는 오직 단 하나의 비밀번호를 사용합니다. Tutanota가 접근할 수 있나요?
되찾기 리셋 비밀번호

No. When a password is used for authentication (login), it is not necessary that it is known to the server you want to authenticate with. The server only needs a fingerprint (hash) of your password. With Tutanota your hash for authentication is calculated by your browser and only the hash is being sent. Your password never travels the Internet in plain text and it is never seen by our server. As hashes are non-invertible, the server is unable to reconstruct your password from the hash. The server is not able to decrypt your message, but still able to log you in.

Recommended for further reading: Learn how Tutanota automates the encryption process while leaving you in full control of your encrypted data.

비밀번호에 어떤 해싱 함수가 쓰이고 있습니까?

Your password is salted and hashed with Bcrypt on your device before being transmitted to Tutanota. Bcrypt is the most reliable method because brute-force attacks need much more time in comparison to conventional methods such as MD5 or SHA. With this method we guarantee an integrated confidentiality and we allow you to access and decrypt your emails from desktops and mobile devices instantly.

어떻게 강력한 비밀번호를 설정할 수 있나요?

Tutanota uses a password strength indicator that takes several aspects of a password into consideration to make sure your chosen password is a perfect match for your secure email account. You can find additional tips on how to choose a strong password here.

Tutanota has no limitations in regard to the password length or used characters; all unicode characters are respected.

Tutanota는 2요소인증을 지원하나요?

Yes, Tutanota supports two-factor authentication with U2F and TOTP. Here are details on how to set up your second factor in Tutanota.

When I log out of Tutanota, the browser or app always logs in again. What can I do to stop this?

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 for automatic login. To 'unsave' the password, please log out. The login screen appears, click on 'More' and 'Delete credentials'.

보안과 프라이버시

암호화 과정은 어디에서 발생합니까?

데이터의 암호화와 복호화는 기기에서 로그인할 때 항상 일어납니다. 모든 데이터는 종단 간 암호화로 암호화되며 오직 당신의 비밀번호로만 데이터에 접근할 수 있습니다.

무엇이 암호화되어 있고 무엇을 읽을 수 있나요?
암호화

Tutanota는 메일함의 모든 데이터 (연락처, 이메일, 이메일 서명, 받은메일함 룰, 청구서 정보, 지불 방법, 인증서 및 고객 도메인의 비밀키)를 암호화합니다. 이메일을 전송할 때, Tutanota는 자동적으로 제목, 내용 및 첨부파일들을 암호화합니다.

저희는 다음의 메타데이터만을 확인할 수 있습니다.

  • 발신인
  • 수신인
  • 이메일 발송일

저희는 미래에 메타데이터를 숨길 수 있는 방법들을 고안하고 있습니다.

제 키는 어디에서 생성되며 비밀 키는 어떻게 보호되고 있습니까?

Your private and your public keys are generated locally within your browser upon registration. Your private key is encrypted with your password. This way your login password receives the status of the private key. The key is encrypted so strong that only you can use the key for encrypting and decrypting data. This is why a strong password is essential. An automatic password check on the client makes sure that you use a strong password. Your password is never transmitted to the server in plain text. It is salted and then hashed with bcrypt locally on your device so that neither the server nor we have access to your password. With this innovative design you can access your encrypted inbox from any device (desktop, mobile) easily.

Tutanota에서는 어떤 암호화 알고리즘을 사용하고 있습니까?

For the email encryption between users, Tutanota uses a standardized, hybrid method consisting of a symmetrical and an asymmetrical algorithm. Tutanota uses AES with a length of 128 bit and RSA with 2048 bit. Emails to external recipients are encrypted symmetrically with AES 128 bit.

제 이메일이 어떻게 Tutanota에서 암호화되나요?

The system automatically encrypts all emails stored in Tutanota. Emails between Tutanota users are automatically encrypted end-to-end, emails to external users can be secured with the help of a password. Here we explain the differences between a confidential (end-to-end encrypted) and a non-confidential email.

Independent of the end-to-end encryption, the transport between client and Tutanota servers is secured with SSL and DANE to maximize security. You can check here how to install the DANE browser add-ons.

Tutanota 서버는 어디에 있나요?

Tutanota 서버는 ISO27001 인증을 받은 독일의 안전한 데이터센터에 위치해 있습니다. 모든 저장된 데이터는 독일의 엄격한 개인정보 보호법을 적용받습니다. 모든 데이터의 독립성은 종단간 암호화로 보장되며 제공 업체인 Tutao GmbH와 제삼자도 읽을 수 없습니다.

암호화된 Tutanota를 익명으로 사용할 수 있나요? IP 주소를 기록하나요?

저희는 로그인 할 때와 이메일을 보낼 때에 IP 주소를 기록하지 않습니다. 발신이나 수신 이메일에서 IP 주소를 제거함으로써 사용자의 위치를 알 수 없도록 만듭니다.

저희의 블로그에서 Tutanota가 어떻게 익명 이메일 서비스를 제공하는지에 대하여 알아보십시오. 회원가입을 할 때, 여러분께서는 휴대폰 번호와 같은 개인정보를 입력할 필요가 없습니다. 또한 저희는 Premium과 Pro 플랜을 비트코인을 통하여 결제할 수 있도록 할 예정입니다.

Tutanota 내에 있는 내 연락처들은 암호화되나요?

Yes, all data within Tutanota is end-to-end encrypted and only accessible with your password. Scanning and profiling of your data is not possible.

Can I disable sessions remotely (session handling)?
IP주소 로그 로깅 보안

Yes. You can view and remotely close active sessions under Settings -> Login.

Check our How-to to learn how to enable storing of closed sessions to monitor whether someone else has access to your account. To guarantee the users' privacy, we have implemented the feature as follows:

  • The IP address is stored encrypted, and only the user can decrypt this information. No one else - not even we at Tutanota - can access this information.
  • IP addresses are only stored for one week and then automatically deleted.
사용하지 않는 계정을 비활성화 / 재사용하나요?

Free of charge accounts are deleted if they were not used for at least six months. Your deleted email address (also if it is an alias) will not be recycled for security reasons. There must be no possibility that someone else is able to register your previously used email address, and then, by accident, receive a confidential email that was meant for you.

Tutanota에서는 왜 이미지 자동 로딩이 차단되나요?

Tutanota does not load images automatically when you open an email. When you load external images manually, please note that

  • someone knows that you read the email.
  • someone may add cookies to your browser (if your browser is not configured to reject them).
  • someone may track your location with your IP address.
  • someone may track parameters of your device.

Please read here how we make sure that you can use Tutanota as an anonymous email service. We plan to improve image loading in the future so that you can whitelist trusted senders; images in emails from these senders are then loaded by default.

If you experiencing issues or bugs with the Android app, updating WebView has a good chance to help.

Here are instructions how to update WebView on your phone.

여러 개의 Tutanota 이메일 주소를 한 계정 아래에 둘 수 있나요?

Yes, you can add existing email addresses (e.g. Alice2, Alice3) as aliases to a Premium account (Alice1). Before you can add the aliases, you need to delete the other accounts (Alice2, Alice3) and specify the Premium account (Alice1) as the take over account upon deletion. We explain here how to take over the email addresses.

Please note: You are only transferring the email addresses. Emails and contacts stored in the deleted accounts (Alice2, Alice3) are being deleted. Please export important emails before deleting the accounts.

How to How-to settings instructions help support

Tutanota is very easy to use. From the start we focused on usability and kept the encryption process in the background. You do not have to install anything or worry about key handling. Tutanota is as easy to use as Gmail or any other webmail service.

You can start with Tutanota right away. If any questions remain, check our detailed how-to.

This describes all Settings of Tutanota. It also answers common usability questions such as:

How to send an encrypted email?
How to switch to not confidential?
How are contacts sorted?
How to add / rename / delete a folder?
How to use multi-select and shortcuts?
How to upgrade to Premium?
How to set up an alias?
How to send an email from an alias?
How to manage passwords for my Premium users?
How to send emails with my own domain?
How to add an encrypted contact form to my website?
How to delete an account?

Tutanota는 왜 pgp를 사용하지 않나요?

Current encryption standards like PGP and S/MIME have several issues that we plan to address with Tutanota. These standards do not support forward secrecy and are not resistant to attacks from quantum computers.

In addition, it is important to us that the subject line in emails is also encrypted. That's why we have developed a solution that is also based on recognized algorithms (RSA and AES) and that automatically encrypts the subject, the content and the attachments. In the future, we plan to upgrade these algorithms to quantum-resistant ones that also support forward secrecy. You can find more information on why Tutanota does not use PGP here.

We also see the importance that Tutanota needs to be interoperable with other encryption solutions. We will develop an API so that Tutanota users can communicate with users of other secure services confidentially in the future.

Tutanota는 어떤 브라우저를 지원하나요? 어떤 브라우저로 외부 수신자가 암호화된 전자 메일을 확인할 수 있습니까?

제가 외부 수신자인 경우, 나중에 다시 제 이메일에 접근할 수 있나요?

Yes, you can always access the emails sent via Tutanota through the link from your latest notification email. Old notification links from the same sender are de-activated for security reasons. Your exchanged password, however, stays unchanged as long as the sender does not change it. If you have saved the password upon accessing your confidential emails in your browser, you do not have to re-enter it.

다른 Tutanota 유저에게 보내는 이메일들은 언제나 암호화되어 있나요?

Can I use plus addresses for my Tutanota email address?

No, Tutanota does not support plus addressing (xyz+username@tutanota.com) for Tutanota domains. If you want to register with different plus addresses at different sites, you can add an alias package to your account (limited to the number of aliases you book). Alternatively, you can use a custom email domain with catch-all to create an unlimited number of plus addresses for incoming emails.

Tutanota는 스패머들로부터 악용을 방지하기 위한 이메일 제한이 있나요?

Yes, Tutanota uses different variables to calculate email limits for individual accounts. This is necessary to protect our free and anonymous email service from spammers who try to abuse Tutanota. If spammers were able to abuse Tutanota, it would harm all Tutanota users - ie Tutanota domains could end up on email blacklists, which we have to prevent under all circumstances.

If you receive the following message in your Tutanota account "It looks like you exceeded the number of allowed emails. Please try again later.", the anti-spam protection method has stopped your account temporarily from sending new emails. Please wait a day or two to send new emails again.

If you need to send more emails immediately, please upgrade to our affordable Premium version (1 Euro per month) as limits for Premium or Pro users are much higher. Simply click on 'Premium' in your top menu bar of Tutanota.

Please note that Tutanota is not meant for sending out mass mailings such as newsletters. Please read our Terms & Conditions for details.

저의 새 계정이 등록 후 48시간동안 대기 상태로 묶여있습니다. 어떻게 해야하나요?

Some accounts are automatically marked for approval upon sign-up to prevent abuse. This often affects IPs from VPN services or Tor as spammers try to bypass our anti-spam protection method by abusing these services. Please read here why the 48-hour wait is necessary to protect your privacy to the maximum with a truly anonymous email service.

During these 48 hours emails cannot be sent or received. Please do not share your new email address before the blocking has been lifted automatically.

I don't receive confirmation emails from services or newsletters. What can I do?

Sometimes newly created email addresses are put on hold for 48 hours to prevent abuse. It is important that you do not share your email address until this block is lifted automatically.

If you do use the email address to register elsewhere or sign up for newsletters before the block is lifted, this service will send you a confirmation email, which will bounce with a temporary error. This might lead to problems registering with this service, even in the future.

Tutanota 가입 시의 캡차는 어떻게 풀 수 있나요?

Tutanota uses its own Captcha so that we do not have to depend on using Google Captcha. This enables us to offer an open source email service without any links to Google.

The Tutanota Captcha shows a clock. You need to enter the displayed time with four numerals, including the colon in the middle. If the displayed time is 8.30 for example, you have to enter 08:30 or 20:30 exactly.
