If you can't sign in to your Google Account, follow these troubleshooting steps.
Erase your device
Important: This option will erase all data — like your apps, photos, and music — from your device. While any data stored in your Google Account will be restored, all apps and their data will be uninstalled. Before you reset, look over the options for restoring your data on a Pixel phone or Nexus device.
Option 1: Remotely reset your device
If your locked device has Android Device Manager turned on, is powered on, and is connected to the Internet, you can remotely erase your locked device’s data.
Option 2: Reset your device to factory settings
You can erase your locked device's data by performing a factory data reset.
