Update Keyring
[Last Updated : 2021-07-31]
Whenever one changes user password the keyring still asks for older password.
This causes annoyance as it ask for password everytime and it never syncs.
Solution
OS - Manjaro
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.
