Hi,
I am a new user of Enpass -- just trying the Linux and Android versions for the first time.
I came to the forums because I noticed two issues on Android that gaetawoo already highlighted above.
This definitely must be fixed ASAP! The fingerprint is a convenience feature, but it is much less secure than a secret like the master password. Fingerprints are quite easy to forge. If an attacker gets hold of my phone and if they are careful, they can already find a template for a fake fingerprint on the glassy surfaces of the phone. That's why Enpass should really reset to requiring the master password to be entered instead of a fingerprint after some time (like 30 minutes) has passed or after a reboot. As it stands now, one can only discourage all users from using Enpass with the fingerprint feature.
I was really surprised by this behavior. The Swype keyboard just shows character after character in clear text in its suggestion bar, while entering the master password! This usually does not happen with password entry fields. It wasn't this bad with the stock Sony Xperia keyboard on my phone.
Please fix these security problems! Apart from these issues Enpass really looks to be the nicest cross platform solution I have seen so far.
