SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you implement robust multi-factor authentication (MFA) to significantly enhance user account security beyond simple passwords.

Core Features & Use Cases

  • MFA Setup: Guide users through setting up TOTP authenticator apps or email/SMS OTP.
  • Secure Login Flows: Integrate 2FA verification seamlessly into your sign-in process.
  • Backup Codes: Provide and manage single-use backup codes for account recovery.
  • Trusted Devices: Allow users to trust devices for a smoother login experience.
  • Use Case: When a user attempts to log in, after entering their password, they are prompted for a code from their authenticator app, ensuring only they can access their account.

Quick Start

Configure the twoFactor plugin in your server and client setup to enable multi-factor authentication.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement multi-factor authentication for user login flows?▼

Multi-factor authentication is implemented by configuring the twoFactor plugin to manage TOTP, email/SMS OTP, and backup codes, prompting users for a verification code after their initial password entry during the sign-in process.

What is the best way to set up TOTP and backup codes for account security?▼

The best way to set up TOTP and backup codes is to use a dedicated MFA lifecycle manager that guides users through authenticator app configuration and generates single-use backup codes for secure account recovery.

How does trusted device management work with 2FA verification?▼

Trusted device management in 2FA verification allows users to mark specific devices as safe, skipping subsequent MFA prompts on those devices to provide a smoother and faster login experience.

Can I use email and SMS OTP alongside TOTP authenticator apps for MFA?▼

Yes, you can use email and SMS OTP alongside TOTP authenticator apps, as the multi-factor authentication setup supports all three methods to secure user accounts and provide flexible verification options.

How do I handle account recovery when users lose access to their 2FA methods?▼

Account recovery when users lose 2FA access is handled through single-use backup codes provisioned during setup, allowing users to securely regain entry and manage their multi-factor authentication settings.
