On Ubuntu, for example if was enabled autologin, may occure situation that annoyng window will appear – Enter password to unlock your login keyring. Usually it appears when you start Chrome browser, save network folder password and so on. In this article I’ll show you how to get rid of that window.
1) In terminal enter commad – seahorse.
2) Click with right button on menu “Login” in Passwords section, and select “change password”.
3) In opened window enter your user password.
4) On the next window left password field empty, click continue and apply a message that password will become unencrypted.
Now that annoying window will not appears.
UPD:
Also you can try delete Login, relogin to system open an app which asks for password and relogin again. On ubuntu 20.04 – that worked for me, and it is much more better, because your password will not be stored in unencrypted form.
