WebAuthn is a browser-based API that allows websites to use built-in authenticators or secure keys to authenticate users. When a user registers, a public-private key pair is generated for the account. The private key is securely stored in the user’s device, while the public key is sent to the server. Then, the server can use the private key to ask the user’s device to sign a “challenge” to verify the user’s identity.
