Security keys are physical devices that provide an extra layer of security for your online accounts. They work by using a protocol called FIDO2, which enables passwordless and username-less authentication. This means you don’t have to remember or type in your credentials every time you log in to a website or service that supports FIDO2. Instead, you just need to insert, tap, or scan your security key to verify your identity.
