PassStrong is a 10$ bluetooth dongle that generates and enters strong password (32 characters, no simple pattern). See here for the key details :

Thanks to the remarks of the previous version, this version has several improvements:

   - pincode to secure the bluetooth connection. The 4 digits code is generated randomly and can be changed (or returned back to 0000, which is the default and means no pincode, for devices not supporting pincode pairing, such as some android phones) by pressing the small button when in the last (and new) section of the settings menu.

   - power saving ability : the device automatically shuts off after 10 seconds. To shut it on, you just need to press the bigger button

   - password erasing : pressing the small button during startup will wipe the pincode & password
