Two-Factor Authentication Plugin for WordPress
The Two-Factor Authentication plugin for WordPress, commonly known as Two Factor, enhances the security of WordPress sites by implementing two-factor authentication (2FA) for user logins. Here's a detailed look at this plugin:
Overview
Two-Factor Authentication adds an extra layer of security by requiring users to provide two forms of identification before being granted access to the WordPress dashboard or any protected area of the site:
- The first factor is typically something the user knows, like a password.
- The second factor is something the user possesses, like a mobile device or a security token.
Features
- Multiple Authentication Methods: Users can choose from various methods like Time-Based One-Time Password (TOTP), SMS, Email, Backup Codes, and even hardware security keys like YubiKey.
- User Control: Users can enable or disable 2FA for their accounts, with the option for site administrators to enforce it for all users.
- Integration: The plugin integrates well with WordPress's core user management system, making it easy to manage without extensive setup.
- Security Notices: Provides warnings and notices for users when they log in from new locations or devices, prompting them to verify their identity.
- Recovery Options: Includes features like backup codes and the ability to disable 2FA from email if the user loses access to their authentication method.
