OAuth flows protected by PKCE
Every social login uses PKCE (Proof Key for Code Exchange). The SDK generates a unique code verifier and challenge pair per attempt. A stolen token is useless without the verifier, which never leaves the browser. Replay attacks and CSRF are blocked at the protocol level.

Extra secure critical actions
Step Up security based on your logic
For critical actions like payments, password changes, and data exports, Auth calls a webhook on your backend. You receive full context. You decide.
Centinaia di percorsi per un’unica destinazione: i tuoi utenti.
