For those complaining that touch ID does not work, have you enabled it I your settings. Also, where the star would be on a calculator in the bottom left corner, theres a fingerprint on the key. Tap that key & a message will pop up asking if you want to allow Touch ID to open Safemail. Touch your home button/fingerprint button & it will open. No one can steal your fingerprint but they get a 4 digit code.
