## Choose your sign-in methods.

Users sign in with a passkey saved on their device or in their password manager. They can start with an email address or select a saved passkey directly.

Send a one-time code to the user’s inbox. They enter the code to sign in, with no new password to remember.

Let users sign in with Google, GitHub, Discord, Battle.net, X, or Steam. Enable the providers that suit your app.

## Ask for the information your app needs.

Configure requests for an email address, name, or other profile details. Users review sharing requests during sign-in; required details need consent before they can continue.

## Connect your application.

Users sign in and review requests to share their information on Sudomimus, then return to your app. Your app manages their business permissions.

Register an application, select its sign-in methods, and add a callback URL. The guide walks through the connection and token handling.
