Tutanota For Mac

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.

Hello yesterday I formatted my mac and downloaded the tutanota desktop app the mac tells me The program 'Tutanota Desktop' can not be opened. Save hide report. Log in or sign up to leave a comment log in sign up. Both Tutanota and ProtonMail can let users send and receive encrypted emails over servers based outside Russia, which make them appealing tools for privacy-conscious users within the country. However, the same encryption may have made them targets of the Russian government, which has been trying to expand its control of the internet. Tutanota hosts all your business emails end-to-end encrypted on our own servers based in Germany. We enable your business to use the benefits of the cloud - availability, cost-efficiency, flexibility, automatic back-up - without compromising on security. With Tutanota you own your data, no. Tutanota and ProtonMail are our two top-rated services when it comes to encrypted email. They’re neck and neck in our roundup of the most secure email providers, and it’s easy to see why. With its all-round end-to-end encryption and its clear focus on open source, Tutanota is the best email provider when it comes to convenience, security and privacy. We have replaced the need for IMAP by building the Tutanota desktop clients for Windows, Linux and Mac OS.

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:

  • end-to-end encrypted mailbox
  • end-to-end encrypted address book
  • automatic end-to-end encrypted emails between users
  • end-to-end encrypted emails to any email address with a shared password
  • secure password reset that gives us absolutely no access
  • full-text search of encrypted data executed locally
  • TLS with support of PFS, DMARC, DKIM, DNSSEC, MTA-STS
  • open source code for the entire client as well as Android & iOS apps

Tutanota combines security with ease-of-use

Tutanota is the secure email service that combines the advantages of the cloud – availability, automatic back-up,auto-sync, cost-efficiency – with the advantages of hosting your emails on your local server – security and data sovereignty.

In the past few months I was thinking to try some new email providers that support end-to-end encryption. I kept reading privacytools.io, with the idea to try some of the solutions listed there.

Then, I finally had the time to start playing around with some of them.

I decided to start with Tutanota. Even though the debate on how much secure is browser cryptography is still active, I’d like to give it a try.

What I like about Tutanota is that you can compile the web UI locally, so it doesn’t reside on their webservers (not that I don’t trust Tutanota, but I prefer to have as much control as possible over my own stuff, even more if it deals with emails and cryptography).

So I followed the instructions on their Github repo (https://github.com/tutao/tutanota/). They have detailed steps on how to do that. Let’s start (I’m assuming that you already have installed git and npm):

Umhh. Step nr. 3 says I have to checkout the branch ‘tutanota-release-2.0.5‘ but it doesn’t appear to be there. Let’s check thought:

Yep. It seems like the branch is no longer there. I’m quite sure they merged the branch into master (didn’t check the commits, sorry), so they need to update the Readme.md file. Anyway, let’s continue.

Cool, step 4 done. Let’s build now:

Ok, nice. I knew nothing about gulp until now. After a quick search, I found out that a simple sudo npm install -g gulp should work. And it worked. So now we can go ahead with our steps:

Sorted! To access the web UI you have to open the index.html throught your favourite browser. I use Firefox, so next steps will be focused on this browser, but you can adapt them to other browsers as well.

First, I wanted to create a brand new profile to use only with Tutanota to segregates data between Firefox instances.

After choosing a name and creating the profile, I created an Automator App like the following image (if you don’t know what Automator is or how to create one, read this link):

The final aspect of my app is:

If you need more security, you can run the newly created Tutanota app in an encrypted container so your browser cache will be encrypted as well, leaving no traces of plain-text emails. But this is a story for the next post.
