Two-factor authentication is a way to add an extra level of security when you log in to your Reddit account. First, you log in with your Reddit username and password. (That’s one factor.) Then, instead of being logged in right away, you’ll be asked for an additional 6-digit authentication code generated from an app on your phone. (That’s the second factor.)

We’ll walk you through the process of downloading an authenticator app and setting things up.
A few things to remember…
Because two-factor authentication is set up using an app on your mobile phone, if you get a new phone you’ll need to disable your current two-factor authentication then set it up again on your new phone.
In case you somehow lose your phone or access to the authentication app you used to set things up, you’ll also get a set of backup codes you can use to log in. Make sure to write down your backup codes and keep them in a safe place. You can generate new backup codes, but only if you’re already logged in to your account, so be careful with them.
