Rate limiting in Better Auth restricts rapid repeated requests to login endpoints. You configure it within the security options to enforce a threshold on sign-in attempts, mitigating brute-force attacks against user accounts.

Securing session cookies involves setting strict attributes within the Better Auth configuration. You define trusted origins explicitly to prevent unauthorized domain access, ensuring session data remains protected against cross-site threats.

CSRF protection in Better Auth validates incoming requests against trusted origins and session tokens. This mechanism prevents unauthorized sites from forging authenticated requests, mitigating cross-site request forgery vulnerabilities effectively.

Better Auth supports secure OAuth configurations for social logins. It provides specific settings to validate tokens, manage redirect domains, and prevent authorization code interception during third-party authentication flows.

Starting a new web app requires configuring a strong secret key, enabling rate limiting, and defining trusted origins. These baseline configurations establish a strong security posture from the outset against common vulnerabilities.
