The Correct Password won't accept even entering it to change some settings

*Avast Free Antivirus Program version: 24.12.9725a (build 24.12.9725.903)

I am trying to change a setting on my Avast account settings but upon entering the correct password at the settings section it kept saying it’s wrong password. What??? I am already signed in to my Avast account what else do I need to do? I am sure I entered it correctly but still it says wrong password. I copied and pasted it. Still wrong password!
