I have wondered how to use a password generator with all my devices and sync them. And, if one or all fail for some reason, to re-install the passwords on the device. How to retrieve password if I use another device which is not normally used by me, say a new device I just got or borrowing another device, like a friends phone, to look at my bank account that requires a password.
So to put it in short form:
1. Sync Password Generator for all devices.
2. Retrieving passwords on another device which does not have my passwords.
3. Retrieving Password Generator with all my passwords that were saved to devices that failed or have been repaired or replace.
