How do I configure email verification in Better Auth to prevent fake sign-ups?▼

Configure email verification in Better Auth by assigning your email sending function to the `emailVerification.sendVerificationEmail` setting, which enforces email access confirmation and prevents fake sign-ups.

What's the best way to implement a secure password reset flow with Better Auth?▼

A secure password reset flow with Better Auth requires implementing timing attack prevention, securing reset tokens, and enforcing session revocation to protect user accounts during the reset process.

How does Better Auth handle password hashing, and can I use Argon2id?▼

Better Auth handles password hashing using the default `scrypt` algorithm, but allows you to implement custom hashing algorithms like Argon2id for enhanced password security and data protection.

Why is client-side validation important for email and password authentication?▼

Client-side validation is important for email and password authentication because it improves user experience by catching input errors early and reduces server load by preventing invalid requests from reaching the backend.

Does Better Auth support timing attack prevention for password reset tokens?▼

Better Auth supports timing attack prevention for password reset tokens by detailing secure reset mechanisms that protect against timing vulnerabilities and ensure proper token security during the authentication flow.
