After (re)starting the Librem 5, after unlocking with the pass code, I get this pop up window:
Authentication required
The login keyring did not get unlocked when you logged into your computer.
Password:
The password for me is the same as the pass code to unlock the screen. I think this “Authentication required” window is a small annoyance that reduces the smoothness of the initial login process. Not really a pain point, but more a paper cut.
