I recently changed my password, using pwd and my root password using sudo pwd root. After that when I reboot, I am asked to enter my keyring password (my old password) at startup. I am guessing that is because the keyring was set to use my old personal password, and now they differ, and the keyring is not automatically unlocked.
Alternatively, you can remove “login.keyring” and “user.keystore” from /home/{username}/.local/share/keyrings/ . Be warned that this will permanently delete all saved keys. After removing the files, simply log out and log in again.
Is this the correct/recommended way for me to solve my problem? I run Cinnamon…
I rebooted again, and this time it did not ask for the old password. I can only assume that, it asked for my old password the first time, to change the password for the keyring to my new password!? So it was just me being impatient, I guess.
