Privacy Review: TutaNota

What is Tutanota?

Tutanota is one of the “up-and-coming” encrypted email providers. What I like about Tutanota is the ability to send emails to anyone – regardless of if they have the encryption keys or not. As the video shows, you can send messages to anyone with a predefined password. You will of course need to communicate with those folks to give them the “secure” password. Tutanota is free right now and has a wonderful app (and is one of the few encrypted services that does). There is a soft spot in my heart for TutaNota – simply because it was one of the first Zero-Knowledge providers that I began to work with. For a free service, they cannot be beat – organization of emails is easy, creating emails is simple, and the app is streamlined. They are missing two very important things: Drafts and PGP Support.

I use drafts all the time. To store data and text from other sources before it is ready to send. The lack of a drafts bin makes it hard for me to use the service, as I need to have everything ready and formed before I actually compose the message. The lack of PGP usage makes the app unusable by people who actually use a PGP key – the tried and true encryption methodology. Several of the other services do a great job of integrating PGP keys and support, hopefully Tutanota will support PGP in coming updates.

I will keep my Tutanota account going for some time, and will keep you all apprized of anything major that happens. Follow my blog and my twitter page for updates.
