Set up an authenticator on Android
- Grab your Android phone or tablet.
- Go to the Google Play store.
- Search for Google Authenticator.
- Download Google Authenticator to your device. Note you may need to log into Google to do this.
Google Authenticator uses the time, as well as other factors, to authenticate you. If your device’s time is different from the time on your service provider’s server, authentication won’t work.
Set the time on your device:
Find Date & Time.
Check that it’s set to Automatic.
Close this window and return to the Setup Wizard.
