Password Manager with USB Keyboard emulation

The idea behind Authorizer is, to use old smartphones as a hardware password manager only. To avoid manual typing of long and complex passwords everytime you need them, Authorizer pretends to be an USB keyboard (e.g. over an USB On-The-Go adapter). With a button press inside the App, it will automatically enters the password for you on your pc, laptop, tablet or main smartphone.
