Login keyring password "no longer matches"
Solution 1:

See here for other cases: https://forum.parallels.com/threads/centos-fedora-mint-linux-login-keyring-issue-the-password-you-use-to-login-to-your-computer.343215/
Solution 2:
One solution is to run this command to reset your keyring password:
rm ~/.local/share/keyrings/login.keyring
