What are security keys?
Security keys connect to your system using USB-A, USB-C, or Bluetooth and they enable extra protection to your online accounts. Companies are making it easier for users to log in to accounts directly using security keys.
When you insert a security key into your computer or connect it wirelessly and press a button on the key, your browser issues a challenge to the key, which includes the domain name of the specific site you are trying to access. The key then cryptographically signs and allows the challenge, logging you into the service.
Many sites support U2F security keys, including Twitter, Facebook, Google, Instagram, GitHub, Dropbox, Electronic Arts, Epic Games, Microsoft account services, Nintendo, Okta, and Reddit.
