Mac not accepting correct Apple ID password
I am trying to log into iTunes on my Mac. A pop-up comes up asking for my apple ID login. Each time I enter my (correct) password, it just asks again/doesn't accept the login credentials. I changed my password several times; it just won't accept it no matter what!! The app store's pop-up is highly annoying as it blocks all windows and doesn't go behind them. I'm using Monterey 12.0.1.
