Learn how to retrieve and generate Google 2FA backup codes with this easy-to-follow, step-by-step tutorial.

Google already provides you an option to use hardware security keys, authenticator apps, prompts on your other devices with Google apps, and SMS-based verification codes as valid 2FA alternatives.
