Security keys are physical devices that you use as your second authentication factor to protect your online accounts from being taken over by bad actors. They are more secure than other methods of multi-factor authentication, such as SMS codes or authenticator apps, because they use encryption to confirm that the key is associated with your account and are resistant to phishing attacks.
