Passwords are now saved in a password manager.

The password manager uses strong encryption using a key derived from the passphrase using
scrypt key strengthening algorithm. This ensures encryption is performed using a strong key
and that brute forcing the passphrase is time consuming.

If the user loses his passphrase no recovery is possible.
