Just a reminder to save your one-time use back up codes in case you get locked out of your account. Many people get new phones and don't remember to transfer their accounts to the 2FA app on their new phone before wiping the old phone.

You should copy and paste them into a text document and save it somewhere. (Preferably not locally on your phone) One Drive or Google Drive is an option. Personally, I print them out and keep it in a secure place.
Once you get back into your account using a one-time use back code, you should reset the Verification code via app using the Manage button. Once you set it up again, you will get a new set of one time-use backup codes and the old ones will no longer work.
