Code exchange

Following a successful registration or authentication operation, your frontend will receive a code. This can be exchanged for an ExtendedPrincipal, representing the outcome of the operation:

frontend/authenticate.ts
import { Passlock } from '@passlock/browser';


const passlock = new Passlock({ tenancyId });


const result = await passlock.authenticatePasskey({
  authenticationToken
});


if (result.success) {
  // send this to your backend
  console.log(result.value.code);
}
backend/authenticate.ts
import { Passlock } from '@passlock/server';


const passlock = new Passlock({ tenancyId, apiKey });


const result = await passlock.exchangeCode({ code });


if (result.success) {
  // will be an ExtendedPrincipal
  console.log(result.value);
}

Using the REST API

Section titled “Using the REST API”

Behind the scenes, exchangeCode makes a REST call to the Passlock API. If you prefer you can make the call yourself:

GET /v2/{tenancyId}/principal/{code} HTTP/1.1
Host: https://api.passlock.dev
Accept: application/json
Authorization: Bearer {apiKey}
