Get Those Backup Codes
For those that have enabled two-factor authentication (2FA) and also tend to use public wifi or travel on a regular basis, today’s tip is for you.

A great example is when you board a flight and connect to the in-flight wifi; when you try to log in, the text message with the special code isn’t going to make it to your phone.
Just about every service that allows 2FA also has special codes that you can use to get in when your phone doesn’t have a cellular connection.
The best place to learn where these special codes exist is the same place that you set up the 2FA for each account.
