A security key is a physical device that gets uniquely associated with your AOL account after you enable it. Each time you sign in with your password, you'll be prompted to approve access to your account using your key. This prevents anyone who doesn't have your security key device from gaining access to your account.

An authenticator app enables two-factor authentication in a different way, by showing a randomly generated and constantly refreshing code, rather than sending an SMS or using another method.
