Android login management tool 1Password has added support for fingerprint authentication in the latest app version.The new version allows users to unlock both the app and the 1Password keyboard with just their fingerprint scanner.Previously, the app only required you to type in a single password to log into numerous accounts.However, the fingerprint unlock function only works on devices that are running Android OS 6.0 Marshmallow.Last November, Password manager app Keeper added support for fingerprint authentication as part of its upgrade version for the latest version of android.
