Tutanota Thunderbird

Today weare hosting an I Love Free Software Day at our offices in Hanover. Since the development of our calendar, you allknow how much we love ice cream. Now we invite everyone in the area to our offices for free ice cream! Get to knowus, have a chat and discuss your most wanted features for Tutanota. The full invitation was sent to you via email. 😉

Giving back on Valentine's Day

Tutanota does not support sending/receiving OpenPGP emails. In addition, there doesn't seem to be any way to read Tutanota emails in Thunderbird or other mail clients. Does such a bridge exist? Microsoft’s Outlook is the de facto email client for most businesses and enterprises, and has been around for decades, with its origins dating back to MS-DOS. Obviously it has tight integration. Tutanota is the world's most secure email service and amazingly easy to use. User account menu. Can I add tutanota services in Thunderbird or any other email client's like fair-email. Posted by 2 days ago. Can I add tutanota services in Thunderbird or any other email client's like fair-email.

The I Love Free Software Day was initiated by the Free Software Foundation Europeto thank all free software developers.As Tutanota is open source as well, lots of developers around the world have contributed to ouropen source email project. We'd like tothank everyone who contributed: You help us build an even better Tutanota every day. If you are interested in helpingus as well, please check our GitHub repository and our job posting.

Open source guarantees security

Open source guarantees that no one can hide an encryption backdoor in the code. That's why we have published the entire client code -web client, Android & iOS apps, desktop clients - under GPLv3 on GitHub.

Only with open source, tech-savvy people can audit the code and verify that Tutanota is doing what we promise:Protecting your private data to the maximum.

Tutanota dependencies

On I Love Free Software Day we would also like to thank all free software developers who are working on the followingprojects:

  • JFBCrypt

We use these projects to build and run Tutanota. So here goes a big 'Thank you!' to the open source community who helpsus realising Tutanota.

Tutanota now comes with dedicated desktop clients

Today we are releasing the first secure desktop clients with built-in encryption for Linux, Windows, Mac OS. This is one of the mostimportant updates since we have first published our secure email service with automatic encryption in March 2014.The new Tutanota desktop clients enable you to use Tutanota directly from your computer without the need of a browser.

Improved security by signing applications

The Tutanota desktop applications for Linux, Windows, and Max OS are signed.You can verify the signature here.The signatures makesure that the desktop clients as well as any updates come directly from us and have not been tampered with.

The client validates the signature before installing any update. This reduces the risk of man-in-the-middle attackseven further as a potential attacker would haveto change not only the client on our server, but also the key, which we publish so people can verify that the keys match.

The code for our desktop clients is published on GitHub as open source, just as the code for our webmail cient andour Android and iOS apps. At Tutanota we believe that using free software is the best way to guarantee maximum security.

Read here why our Google-free Android app makes Tutanota one of the best for open source emails.

Secure desktop clients based on Electron

When we decided to build desktop clients for Tutanota, we carefully evaluated whether to build a native client foreach OS or use Electron to convert our webmail client into desktop clients for Linux, Windows and Mac OS. We haveopted to use Electron for the following reasons:

  • We are able to support all three major operating systems with minimum effort.
  • We can quickly adapt the new desktop clients so that they match new features added to the webmail client.
  • We can allocate development time to particular desktop features, e.g. offline availablity, email import, thatwill simultaneously be available in all three desktop clients.

Native desktop clients have a slight advantage towards clients built with Electron in regards to RAM, but thisadvantage does not outweigh the fact that with Electron we can support all three operating systems with miminumdevelopment effort. On top of that, we have put special attention to this issue when redesigning our new webmailclient in 2017 and 2018 so that the current desktop versions of Tutanota need relatively little RAM.

At Tutanota we are a small team so we have to focus on how to develop the best product with miminum effort, andElectron enables us to achieve just that.

Please note that if you open several instancesof the desktop client, only the instance that has been opened first saves data if you choose to save the loginpassword or create a search index. At the moment, the additional instances only use a temporary cacheso that such data is not saved when you close the desktop client again.

After releasing the first basic version, wewill now focus on adding typical desktop features to the clients.

Email import and synchronization with external mailboxes

The next feature on our development roadmap for the desktop clients is email import and synchronization with externalmailboxes. The import feature via the Tutanota desktop clients will enable Tutanota to import emails from external mailboxesand encrypt the data locally on your device before storing it on the Tutanota servers.

This feature is very important to us as it will let you import and encrypt external data in Tutanota without our serversever being able to see or read your data.

The Tutanota webmail client does not support such an import feature because with the webmail version it is impossible to encryptimported data before it hits the server.

Offline availability with the desktop clients

The desktop clients also give us the possibility to add offline support to Tutanota. In the future, you will beable to access and view your encrypted mailbox even when you have no access to the Internet via our dedicated desktop clients.

Perfect email alternative to privacy-invading services

To provide the best privacy-focused email service, we are taking every step of your email usage intoaccount. We are never making a trade-off when it comes to security while focusing on your convenience and ease-of-use.

The combination of security with ease-of-use is the reason for Tutanota's continuous growth as well as for thesteadily growing number of end-to-end encrypted emails sent by our users.

Secure desktop clients support same features as webmail client

Automatic synchronization for your encrypted mailbox

Your encrypted mailbox is automatically synchronized between the desktop client, the webmail client and the Androidand iOS app. No matter where you manage your encrypted emails, your mailbox is updated instantly on all devices.

Short-cuts for ease of use

The new desktop clients support all short-cuts that you are used to from the webmail version. Simply press F1 (Fn+F1)to view all available short-cuts in any opened window.

Two-factor authentication

Tutanota supports 2FA (U2F & TOTP) to further secure your email login. We recommend that you use a hardware token(U2F) as U2F is the most secure form of two-factor authentication.

The beta desktop clients do not support U2F right now.The reason is a known issue with WebAuthN that we plan to fix in the coming months.

Security features that make Tutanota stand out from the crowd

By making sure that all your data is always end-to-end encrypted, only you own your data.

On top of the built-in encryption, Tutanota's secure password reset andinnovative search on encrypted data are just two important features that make surethat no third party - not even we - cangain access to your data.

Here are the most important features that make Tutanota's security unrivaled:
