open the app failure

hi everyone, when i go to the open the “open the app” tab in passwords i get a box up automatically showing an email address and asking me for my account password, it says “please log in with your avast account to continue sync and backup”, i dont want to sync and back up anything, the problem is that the email address it shows is the wrong one, and i cant find a way to change it,this happens on chrome and firefox, so i dont want to sync and back up anything, and its also the wrong email address that i cant seem to change, any suggestions please.

You can change your email address in your my.avast.com portal.See if this helps you set up the correct email address:
