motorola moto g3 I can't log in to my google account

Hello, I have a problem with Motorola, I bought a phone at a pawnshop, it was not within range after inserting the card, turning off nothing changed. I did a hard reset, just a problem because you have to log in to the gmail account that was used on it before and I don't have access to it. What to do to work around this and to log in to another account. Android 6.01.

And what model is it?

Look for "Reset FRP" on Google

The previous owner has restored the phone to factory settings, but has not previously deleted his google account. This is called Google Account Lockout. If the phone is legal, it is best to ask Lombard to contact the previous owner. You can also bypass the lock through a usb host with a special file.
