Users

Once a user has successfully logged in, the SDK can be used to view and manage that user's information, add additional authentication factors, or delete factors that are no longer used.

Methods

To call these methods, Manage user data must be enabled in the SDK Configuration page of the Stytch dashboard.

Get user

The SDK provides synchronous and asynchronous methods for getting a user. The recommended approach is to use the synchronous method, user.getSync, and listen to changes with the user.onChange method.

If logged in, the user.getSync method returns the cached user object. Otherwise it returns null. This method does not refresh the user's data.

The user.getInfo method is similar to user.getSync, but it returns an object containing the user object and a fromCache boolean. If fromCache is true, the user object is from the cache and a state refresh is in progress.

The user.onChange method takes in a callback that gets called whenever the user object changes. It returns an unsubscribe method for you to call when you no longer want to listen for such changes.

In React, the @stytch/react library provides the useStytchUser hook that implements these methods for you to easily access the user and listen for changes.

The asynchronous method, user.get, wraps the get user endpoint. It fetches the user's data and refreshes the cached object if changes are detected. The Stytch SDK will invoke this method automatically in the background, so you probably won't need to call this method directly.

import React from 'react';
import { useStytchUser } from '@stytch/react';

export const Home = () => {
  const { user } = useStytchUser();

  return user ? <p>Welcome, {user.name.first_name}</p> : <p>Log in to continue!</p>;
};

Update user

Wraps Stytch's update user endpoint. Use this method to change the user's name, untrusted metadata, and attributes.

You can listen for successful user updates anywhere in the codebase with the stytch.user.onChange() method or useStytchUser() hook if you are using React.

Note: If a user has enrolled another MFA method, this method will require MFA. See the Multi-factor authentication section for more details.

Delete authentication factors

Wraps Stytch's delete authentication factors family of endpoints and can be used to remove factors from a user.

These methods cannot be used to remove all factors from a user. A user must have at least one email, phone number, or OAuth provider associated with their account at all times, otherwise they will not be able to log in again.

You can listen for successful user updates anywhere in the codebase with the stytch.user.onChange() method or useStytchUser() hook if you are using React.

Note: If a user has enrolled another MFA method, this method will require MFA. See the Multi-factor authentication section for more details.
