OneMoreSecret app
OneMoreSecret is Security application that is open source under the MIT license.OneMoreSecret is a standalone security layer for your data (e.g. passwords, more to come). It leverages the Android Keystore system, turning your phone into a hardware security module. In other words: with OneMoreSecret, you decrypt your secrets with your phone and your fingerprint.
No risk of compromising your entire password database through master password leak - every password is encrypted separately. Instead of a master password, OneMoreSecret relies on asymmetric cryptography.
Send the encrypted password to your smartphone from your PC through a sequence of QR codes, decrypt it and type the password backto the PC using a virtual Bluetooth keyboard.
