For added security, turn on Screen Lock by storing your password in the Tutanota app. Then go to Settings > Login and choose your Unlock method. When Screen Lock is enabled, you’ll be required to open Tutanota similar to how you would unlock your phone – by entering your PIN, password, Touch ID, or Face ID.

Happy encrypting. 🔒
