email-and-password-best-practices

To implement secure email verification in Better Auth, configure the emailVerification.sendVerificationEmail setting to dispatch a verification email to the user. This enforces email access and prevents fake sign-ups.

To prevent timing attacks during a password reset, implement specific security considerations for the reset flow, including token security measures and immediate session revocation upon a successful password reset.

Yes, Better Auth supports Argon2id for password hashing. It uses scrypt as the default hashing algorithm but provides configuration options to implement custom algorithms like Argon2id for enhanced security.

Handling callback URL security involves addressing callback URL validation during the email verification configuration to ensure secure redirection and token handling after the user completes the verification process.

Yes, you should revoke existing sessions when a user resets their password. Session revocation on password reset is a critical security consideration enforced within the password reset flow to protect user accounts.

Yes, client-side validation is needed for email and password authentication. The implementation addresses client-side validation alongside server-side security rules to ensure robust user account security and prevent invalid inputs.
