EA app won't let me log in

Hi!

I just downloaded the EA app on my new MacBook and it simply won't let me log in when it says "EA app wants to make changes. Please enter your password to allow it.". I checked multiple times, I am putting the correct username and password down, but it won't let me in. I already tried renewing my password and deleting, then re-downloading the app. I am out of ideas. What should I do?
