== Password Vault==
This app stores your passwords, protected by FingerPrint scan (if you have set it up) and a Master Password.\\
The Master Password is only stored in encrypted form, not in plaintext.\\
Similarly your site/app passwords are only stored in encrypted form.\\
The encryption keys are not in the code (the keys are your Master Password plus your DeviceID).\\
After providing your Master Password, you can add sites/apps and passwords.\\
Touching an entry in the list of sites and passwords shows a dialog\\
where you can copy the password to the clipboard (to pass into the app/site)\\
or edit the entry and save, or delete.\\
\\
Requires the Biometric plugin (or you could comment out that code)\\
