Description of my issue:
I have set up two-factor auth on one of my android devices and it worjs flawlessly.
Nevertheless, a second installation on a different devives yields codes which are not valid, although the account name and the key are both correct.
If this method of auth can only work with one device, than it cannot be impemented in scenarios where multiple backend users need to log in.
