Use public key cryptography and Web Authentication instead of a password

The Web Authentication API (WebAuthn) is a specification written by the W3C and FIDO.

The WebAuthn API allows servers to register and authenticate users using public key cryptography.

Public Key Cryptography uses the concept of a keypair. A private key that is stored securely with the user and a public key that can be shaed with the server. Those 'keys' are long, random numbers that have a mathematical relationship with each other. Want more information on the whole WebAuthn process? Visit webauthn.guide/

As of December 2019, WebAuthn is supported on Edge, Firefox, Firefox Android, Chrome, Chrome Android, Safari, Opera and iOS Safari for iOS 13.3. Visit caniuse.com for more information.
