SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the complexity of implementing secure multi-factor authentication (MFA) by providing standardized patterns for TOTP, OTP, and backup code management.

Core Features & Use Cases

  • Multi-Method Support: Configure TOTP authenticator apps, email/SMS OTP delivery, and secure backup codes.
  • Security Hardening: Manage trusted devices, rate limiting, and encrypted storage for sensitive authentication tokens.
  • Use Case: Integrate robust 2FA into a user sign-in flow to ensure that accounts remain protected even if passwords are compromised.

Quick Start

Use the two-factor-authentication-best-practices skill to configure the Better Auth twoFactor plugin with TOTP and email OTP support for your application.

FAQPage Schema
How do I configure TOTP and email OTP for multi-factor authentication?

Configure multi-factor authentication by setting up the Better Auth twoFactor plugin to manage TOTP authenticator apps, email-based OTP delivery, and backup code recovery systems within your user sign-in flow.

What is the best way to implement backup code recovery for 2FA?

The best way to implement backup code recovery is by using standardized patterns within the Better Auth framework that provide encrypted credential storage for sensitive authentication tokens and secure recovery options.

Does Better Auth support trusted device management for MFA?

Yes, Better Auth supports trusted device management for MFA by applying security hardening measures that manage device trust, handle secure sessions, and enforce rate limiting during the authentication process.

Can I use this approach to secure user identity if passwords are compromised?

Yes, you can integrate robust two-factor authentication into your user identity management to ensure web application accounts remain protected even if user passwords are compromised.

How does encrypted credential storage work for authentication tokens?

Encrypted credential storage works by securely managing sensitive authentication tokens and backup codes during multi-factor authentication, applying security hardening protocols to protect user identity data.

What are the limitations of email-based OTP in multi-factor authentication?

Email-based OTP limitations in multi-factor authentication are mitigated by combining it with TOTP and backup code recovery, while applying rate limiting and device trust management to secure the authentication flow.
