To enforce email verification, configure the requireEmailVerification setting in your Better Auth configuration to block sign-ins until the user verifies their email address, reducing sign-up abuse.

Implement secure password reset flows by configuring sendResetPassword with strict token expiry limits in your backend authentication setup. This ensures tokens are invalid after a short window, protecting against unauthorized access.

Security hardening for email and password authentication includes setting token expiry, validating redirect URLs, enforcing password policy defaults, and enabling revokeSessionsOnPasswordReset to invalidate active sessions after a credential change.

Yes, Better Auth supports revoking active sessions upon password reset. By enabling the revokeSessionsOnPasswordReset configuration, the system invalidates all existing user sessions immediately after a successful password reset.

Yes, Better Auth is applicable to backend services supporting both web and mobile apps. You can configure sendVerificationEmail and sendResetPassword flows to securely manage authentication across mobile platforms.

Password reset redirect validation fails when the target URL is not explicitly whitelisted in your authentication configuration. You must validate redirect URLs to prevent open redirect attacks during the password reset flow.
