Trouble with keyring

[IHaveALinuxPhone]

Geary quit downloading email from my Gmail account on both Manjaro and Arch, reporting a keyring error and asking for a password.  Neither my login password nor my Gmail password was satisfactory. It used to work. I renamed Default_keyring.keyring in .local/share/keyrings. But no joy.  Then I tried sudo pacman-key --init and then sudo pacman-key --populate. But still no joy. Advice?

Crap. I made it worse. Now I can't get into Arch anymore. I never changed alarm's publically published password. It must have been the pacman-key commands.

Weird. Now I can get in. I have no idea what's going on.

This is a fairly common problem, even on desktop GNU/Linux. If it happens again, a brief Internet search should turn up plenty of results.
