Why You Need Secure Email

Email encryption makes sure that your private emails can only be read by yourself and the intended recipient. On top of that, using a secure mailbox protects you from online attackers and identity theft. As we explain in our Email Security Guide, keeping your mailbox safe is crucial. Many services let you reset your password via email, which makes your email account the gate to your online identity. That’s why email services must focus on security, and that’s what we at Tutanota do. By encrypting all your emails automatically and by offering best-in-class login protection, you can rest assured that your Tutanota emails are safe.

Please find more details on our high level of security.

We at Tutanota do not offer password resets via email – for obvious security reasons. Please make sure to write down your recovery code when signing up for a secure mailbox.
