Code instructions

const client = new StupidWebauthnClient();

Register email address

<form>
  <input name="email" type="email" required />
</form>

const email = e.target.email.value;
await client.Register1EmailChallenge(email);
// send email

Run on opening at the validation link:

import queryString from "query-string";

const params = queryString.parse(location.search) as { c?: string };
// check if token is add to the url
if (!params.c) throw "Invalid email verification url provided";
// validating email
await client.Register2EmailVerify(params.c);
// email registered successfully
// creates an `swa_auth` cookie

Register passkey

const res1 = await client.Register3PasskeyChallenge();
const res2 = await client.Register4PasskeyRegister(res1);
await client.Register5PasskeyVerify(res2);
// passkey authenticated

Login

<form>
  <input name="email" type="email" required />
</form>

On form submission:

const email = e.target.email.value;
const res1 = await client.Login1Challenge(email);
const res2 = await client.Login2Authenticate(res1);
await client.Login3Verify(res2);
// authenticated
// creates an `swa_auth` cookie

Authentication

Check if the swa_auth cookie is valid

client
  .AuthValidate()
  .then(() => {
    // is authenticated
  })
  .catch((err) => {
    // navigate back to the login page
  });

Authentication with csrf blocking

await client.AuthCsrfChallenge();

// Or any api call that uses the csrf validate middleware
await client.AuthCsrfValidate();

Double Validation

// assuming that the client is authenticated
const res1 = await client.AuthDoubleCheck1Challenge();
const res2 = await client.AuthDoubleCheck2Authenticate(res1);
await client.AuthDoubleCheckVerify(res2);
// creates an `swa_doublecheck_auth` cookie that is valid for a minute
// Now make a request to your server which requires an extra check to validate

Logout

await client.Logout();
// Navigate back to the login page

Passkey invalidation

// Removes all passkeys, invalidates all session cookies and logs out
await AuthDoubleCheck123();
await AuthPanic();

// Removes current passkey and logs out
const res1 = await AuthDoubleCheck1Challenge();
const res2 = await AuthDoubleCheck2Authenticate(res1);
await AuthDeletePasskey3(res3);

GDPR Request

// Data Request
await AuthDoubleCheck123();
await GdprData();

// Data Deletion Request (will delete the account after 30 days)
await AuthDoubleCheck123();
await GdprDeleteSet();

// Retract Deletion Request
await AuthDoubleCheck123();
await GdprDeleteUnset();
