Yo Garrett - if you use Google Authenticator and I agree with
@Juro thats it’s the best, it’s super important to know that if you update your phone, you have to export your Authenticator keys before you give up your old phone. It’s a nightmare to fix that problem if you don’t know to do so and a lot of people don’t know that. You can’t just “sign in” to Authenticator on your new phone and have your keys/codes there.
