How do I enter the password for mail on mac?
I deleted one of my email accounts a while back but since then get constant reminders that it is not connecting. I have tried to recreate the password but can not enter it in Internet Accounts of System Preferences. My Mac is on OS version 10.11.6 and is not getting updated. I have fallen foul of Google’s OAuth 2,0 policy. Below is the error message I get when trying to enter the password for mail on mac “Authorisation Error Error 400: invalid_request You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure. You can let the app developer know that this app doesn't comply with one or more Google validation rules.” What is the fix that will restore my email account and password?
I have the entire mac backed up for the past four years. Which bit do i restore and can I find out the password I was using before the pandemic?
iMac, OS X 10.11
