Next time you buy a used phone, first have the seller remove their account to avoid FRP:
1. Remove any PIN or swipe pattern for the lock screen
2. Go into Settings - Accounts and remove all accounts
3. Then factory reset the device.
After that it shouldn't ask for the email and password with Factory Reset Protection.
