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 TLS to maximize security.
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:
Tutanota does not load pictures automatically when you open an email. When you load external images manually, please note that
Here we explain how to display external images. 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.
Phishing is a name or type of online scam in which criminals try to look like a legitimate sender in order to get your data such as credentials or credit card data. Phishers use very sophisticated psychological techniques and develop very realistic copies of real websites and emails.
If you see a phishing banner, it means that some parts of this email match our phishing signatures after other users reported similar emails as phishing. Please be extremely careful with such messages. Usually phishing emails contain a special link to the website which looks real but it actually is not. If you think that the email is legitimate and you opened the link, please make sure to check the full website URL: Check that you see all of it, sometimes only one part or one character may be swapped. Here is more information on how to prevent email phishing attacks.
You can mark an email as not phishing so you will not see the warning message any more for this email.
We never send you emails with links where you need to type in your password. We encourage you to always protect your login credentials with 2FA as this makes it close to impossible for an attacker to log into your account.
If you already fell for a phishing attack, please check this FAQ.
We require all messages to be authenticated. Without authentication, the email could be coming from anyone or could be modified so you should always treat such emails with scrutiny. If you see a message where the authentication has failed (red warning banner), you should be especially careful as it means that this email was likely faked.
Yes, Tutanota comes with full-text search of your encrypted mailbox. In the free version, search is limited to four weeks into the past due to heavy server load caused by the encrypted search feature. Learn here how you can improve your search results. The spam folder is excluded from search.
Search is executed locally via an encrypted search index to guarantee security and privacy of your data as well as your search queries. As the search index needs to be stored in your browser, it does not work in private mode/incognito mode. Read here how our innovative full-text search on encrypted data works.
The Settings are in the navigation menu to the left.
The language in Tutanota is taken automatically from your browser or system settings. Please change the language there. Alternatively, you can go to 'Settings' -> 'Appearance' to switch the displayed language for Tutanota.
We also invite you to join our translation project to improve Tutanota in your native language!

WebView is a system app on Android devices which allows us to display web content inside the Tutanota app. Newer versions let us use newer technologies to make the app smaller, faster, more beautiful and more reliable. If you experiencing issues or bugs with the Android app, updating WebView has a good chance to help.
In the mobile app, you can currently only login with one user. To switch to another user, you must log out and log in again. You can login with multiple users in the browser by opening several tabs or windows. In the desktop clients, you can also open several windows to login with multiple users.

那里解释了 Tutanota 的所有设置项，也回答了像以下这些常见问题：
而且，我们认为邮件标题的加密也是非常重要的，因此我们开发了一套基于知名算法（AES 和 RSA）的解决方案，能够自动加密标题，正文和附件。在未来我们计划升级加密算法使其不被量子计算机破解且支持更新的保密性。 你能在这找到关于 Tutanota 为什么不使用 PGP 的更多信息。

Alternatively, you can use a custom email domain with catch-all to create an unlimited number of plus addresses for incoming emails.
是的，任何 Tutanota 付费订阅都可以使用自有域名。一经升级，你可以无限制地添加你的域名。
Yes, Tutanota uses a spam filter to keep your mailbox free from spam. We are improving this filter continuously. Should you receive spam emails in your inbox, you can also configure your own spam rules here to deny or allow certain email addresses or domains. If a sender is blocked (rejected) by the spam filter, you can allow the sender for your account.
In paid accounts, only admins can create spam rules that are being applied across all users.

Yes, with a paid subscription you can set up email notifications to any email address under 'Settings' - 'Email' - 'Notifications'. You will be informed about new emails once until you log in. Only if you have logged in to view this email, Tutanota will send another notification to keep notification emails to a minimum.

Check here to see how you can upgrade or downgrade and how to add or disable extra bookings (aliases, storage, additional users).
Please check whether the sender was blocked by following this instruction.
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.
Most websites and online services let you register with your chosen Tutanota email address just fine. Unfortunately, we have received reports by users that some websites block Tutanota email addresses for registrations. Please check these options to resolve this situation.
Tutanota 使用自己的验证码, 这样我们就不必依赖于使用谷歌验证码。这使我们能够提供开源电子邮件服务，没有任何 Google 链接。
Tutanota 验证码显示一个时钟。您需要使用四个数字输入显示的时间，包括中间的冒号。例如, 如果显示的时间为 8.30, 则必须准确输入 08:30 或 20:30 。
