Sign-up and Sign-in

User registration and sign-in are performed through the signin method.

FP

import { signin } from "@noauth/browser";

const { verified, accessToken } = await signin("[email protected]", {
  apiKey: "your-api-key",
});

if (verified) {
  console.log("User authenticated with token:", accessToken);
}

OOP

import { NoAuth } from "@noauth/browser";

const noauth = new NoAuth({ apiKey: "your-api-key" });

const { verified, accessToken } = await noauth.signin("[email protected]");

if (verified) {
  console.log("User authenticated with token:", accessToken);
}

signin returns an object with the following properties:

• verified: boolean indicating if the user has successfully passed the authentication challenge.
• emailVerified: boolean indicating if the user's email has been verified correctly. Defaults to false and changes its value after the user has completed any OTP flow.
• accessToken: a JWT (JSON Web Token) that can be used to authenticate your users' requests on your server. Read more about Access Token.

Authentication flow

Under the hood, signin implements a complex authentication flow based on WebAuthn and certified by FIDO2. This flow can be expressed in a sequence diagram like the following:
