the Biometic Lock is really cool, I don't have to enter the password ever time. But should we then have not a possibility to really log out for entering the password again. But if don't have to enter the masterpassword for some month, you will have difficulty to remember it.
I know I can write it on a paper at my home. But if I'm outside and without a iPhone.
Perhaps a setting, where can I choose, if I have to enter it every n-day. But as said before Biometric Lock is awesome.
