Turalogin is a hosted passwordless authentication service that provides simple email-based authentication without OAuth's complexity. OAuth is powerful but complex. Turalogin delivers authentication without the redirect dance, token refresh logic, or provider-specific quirks.
OAuth was designed for authorization (granting access to resources), not authentication. Using it for login adds significant complexity:
Register your app with each provider. Configure client IDs, secrets, scopes, and callback URLs. Different for every provider.
Redirect to provider → user authorizes → redirect back with code → exchange code for token. Users leave your site, breaking the flow.
Store access tokens, refresh tokens, and token expiration times. Implement refresh logic when tokens expire. Handle revocation.
Google, GitHub, Facebook. each has different APIs, token formats, and error handling. Supporting multiple providers multiplies complexity.
Callback URLs differ between environments. Testing OAuth locally is painful. Provider configurations break when deploying.
Users stay on your site. Enter email, click link from their inbox, they're authenticated. No provider consent screens.
One API key works everywhere. No client IDs, no secrets per provider, no callback URL configuration.
Turalogin verifies identity and hands you the email. You create your own session that lasts as long as you want. No refresh logic needed.
No callback URL configuration. Test locally without ngrok or special setup. Same code works in development and production.
/auth/start to send the login link. /auth/verify to validate the token. That's the entire integration.

Pro tip: You can use Turalogin for authentication and OAuth for specific integrations. Let users log in with Turalogin, then optionally connect their GitHub/Google accounts for specific features.
