email-and-password-best-practices

To implement secure email and password authentication with Better Auth, you must configure email verification, secure callback URLs, and select password hashing algorithms like scrypt or Argon2id. Setup involves assigning your email sending function to emailVerification.sendVerificationEmail.

Preventing timing attacks in a password reset flow requires implementing robust token security and consistent response timing. This skill provides configuration examples for secure password reset mechanisms that explicitly protect against timing attack vulnerabilities.

Email verification prevents fake sign-ups by enforcing mandatory email validity before granting user access. You configure this by setting the emailVerification.sendVerificationEmail property to your custom email sending function, ensuring only users with valid emails can register.

Yes, you can use Argon2id instead of scrypt for password hashing. While scrypt is the default hashing algorithm provided, this skill offers custom algorithm options that allow you to configure Argon2id for your specific security requirements.

Yes, Better Auth supports mandatory email verification for new user registration. This skill guides you through enforcing email verification to ensure user email validity and securely manage the registration system.
