email-and-password-best-practices

Email verification in Better Auth is configured by enabling the emailAndPassword plugin and wiring the emailVerification.sendVerificationEmail function. You can optionally enforce requireEmailVerification to block sign-in until the user confirms their email link.

Implement secure password reset handling in Better Auth by configuring the sendResetPassword function. This setup ensures reset requests use tokens with expiry limits, can revoke existing sessions, and trigger event hooks for reliable credential recovery.

Yes, you can override the default password hashing in Better Auth by providing custom hash and verify functions. This allows you to implement stronger algorithms like Argon2id and enforce specific password length requirements while planning safe migrations.

Better Auth supports session revocation during password reset by utilizing event hooks within the sendResetPassword flow. This mechanism ensures that existing user sessions are securely invalidated when a lost-password request successfully processes.

Yes, you must run database migrations after enabling emailAndPassword and configuring email verification or reset policies. Execute npx @better-auth/cli@latest migrate to apply the required authentication schema changes to your database.

Securing email and password authentication involves enforcing email verification before access, configuring password resets with token expiration, and overriding default hashing with Argon2id to ensure user identity assurance and safe credential recovery.
