Cant login due to security issue
Google account via admin.google.com – the Admin console.
Click ‘Users’
Click the user you wish to gain access
Click ‘Security’
Click ‘2-step verification’
Click ‘Get Backup Verification Codes’
Copy out the codes
‘Copy all’ to a text/Word/editor (you’ll need one shortly),
Log out.
Log into the account you’re trying to access. It will now ask you to enter one of the backup codes. Do that. You’re in!
