Manage Metadata with Lock

Learn how to manage user and app metadata with the Auth0 Lock library.

You can use the Lock library to define, add, read, and update the user_metadata. You can read the user’s user_metadata properties the same way you would read any other user profile property. For example, the following code snippet retrieves the value associated with user_metadata.hobby and assigns it to an element on the page:

// Use the accessToken acquired upon authentication to call getUserInfo
lock.getUserInfo(accessToken, function(error, profile) {
  if (!error) {
    document.getElementById('hobby').textContent = profile.user_metadata.hobby;
  }
});

You can use additionalSignUpFields to add custom fields to user sign-up forms. When a user adds data in a custom field, Auth0 stores entered values in that user’s user_metadata. To learn more about adding user_metadata on signup, read Additional Signup Fields.
