Steps to reproduce:

1. Have three devices (two computers and one mobile phone).
2. Imagine one computer and a mobile phone are your personal and one computer is e.g. one at work/computer café.
3. Log in to your personal computer (tick keep logged in).
4. Log in to your mobile phone (there is no keep logged in, but the log-in state is kept automatically).
5. These two devices are working, you can use them together, everything works as expected.
6. Log in to the third device (computer at work/computer café).
7. Log out from the third device.

Expected behavior:
You stay logged in on your two devices, you are only logged out from the third one.

Current behavior:
Once you hit log out on any device, you are automatically logged out from all devices (also from your personal ones and ones, where you ticked keep logged in checkbox when logging in).
