Login
initially
my password works and then going to another screen and asking to login again
Hi,
Accountsd asking you often…
Just open the "Keychain Access", click right on the "login" keychain in the sidebar, select "Change settings for Keychain "login"" and unselect both options "Lock after ..." and "Lock when sleeping". – Tom Kraina Sep 8 '16 at 10:55
If your Mac keeps asking for the login keychain password
The password of your macOS user account might not match the password of your login keychain. Either create a new login keychain or update it with your new password.
