This guide shows you how to use the credentials manager to store and Refresh Tokens.

Auth0.swift provides a utility class to streamline the process of storing and renewing credentials. You can access the accessToken or idToken properties from the Credentials instance.

When your users log in successfully, save their credentials. You can then log them in automatically when they open your application again.

To get a Refresh Token during authentication, use the offline_access scope. You can use the Refresh Token to request a new Access Token when the previous one expires.

First, import the Auth0 module to the file that will present the login page:

Next, present the login page:

When the user opens your application, check for valid credentials. If they exist, you can log the user in automatically and redirect them to the app's main flow without any additional login steps.

First, you check if the credentials manager has valid credentials:

Next, retrieve the credentials:

If the credentials have expired, the credentials manager will automatically renew them for you with the Refresh Token.

When you need to log the user out, remove their credentials from the keychain:

To get the user's profile, you need a valid Access Token. You can find the token in the credentials object returned by the credentials manager.

To show the information contained in the user profile, access its properties, for example:

You can request more information than returned in the basic profile. To do this, you will be accessing the Auth0 Management API.

You will need to update the original login scopes to include read:current_user to gain access to the full profile data and update:current_user_metadata to gain access to patch this data.

You will also need to change your audience to the API Audience identifier for the Management API. The default identifier is https://YOUR_DOMAIN/api/v2/

Putting this all together you should have a login that looks like:

You can add custom user information in the user metadata section by performing a patch:

The user_metadata dictionary contains fields related to the user profile. You can specify the fields you want to retrieve, or use an empty array [] to pull back the full user profile.

Retrieving the user_metadata dictionary:

Accessing the user's metadata. You can choose the key names and set the appropriate type for the user_metadata dictionary data.
