When Google Prompt is enabled, you will get a message on your phone asking you if it is you signing in. You would then tab Yes, and you would then be signed into your account. Note: you need an Android phone to use this method. Click on "Chose another option", then select "Google Prompt".  Setting this will allow you to access your google account even if Google Prompt is not available. Follow the on screen instructions if you want to use text messages or a phone call for the backup option. You can use backup codes instead of a text message by selecting "Use Another Backup Option".
