What to Do Next

You have a running instance of FusionAuth and an admin account. If you haven't finished First Time Setup yet, start there. Then pick the task that matches your next goal.

Add Login to Your App#

• Follow a quickstart for your language or framework. Each quickstart adds login and logout to a sample app.
• Add an application in the Admin UI. Every app that users log into needs an application in FusionAuth.
• Decide between the hosted login pages and the Login API.
• Learn how FusionAuth works: tenants, applications, users, and registrations.

Create and Manage Users#

• Let users sign themselves up.
• Register a user and log in with the API.
• Verify email addresses before users can log in.
• Bring existing users from another system with a migration.

Call the API#

• Create an API key in the Admin UI.
• Install a client library for your language.
• Browse the API reference.

Add Login Methods#

• Enable passkeys or one-time passwords.
• Require multi-factor authentication.
• Let users log in with Google, Apple, or another identity provider.

Control Access#

• Give users roles in each application.
• Learn the other options in Authorization.

Customize the Experience#

• Match your brand with a theme for the hosted login pages.
• Configure an email server and customize the email templates.
• Add claims to tokens with a lambda.

React to Changes#

• Send webhooks to your app when users log in, register, or change.

Protect Your Users#

• Turn on CAPTCHA and rate limiting.
• Review the other options in Security.

Prepare for Production#

• Write tests that run against a real instance.
• Plan your production deployment.
• Harden your instance before customers log in.
