LaunchFa.st comes with baked-in **Google OAuth 2.0**, **Twitter OAuth 2.0** and **Credentials (Email and Password) Authentication APIs** to help you authenticate your users.

**Twitter OAuth 2.0** Authentication method uses Twitter APIs to communicate (all **server-side**) and creates a cookie with a signed session, ensuring that your user data is secure and only present for the logged in sessions.

**Google OAuth 2.0** Authentication method uses Google APIs to communicate (all **server-side**) and creates a cookie with a signed session, ensuring that your user data is secure and only present for the logged in sessions.

The **Credentials (Email and Password)** Authentication method uses baked-in APIs to communicate (all **server-side**) and uses Upstash to sync the authentication related data such as hashed passwords, ensuring that your user data is secure and reliable.
