Two-factor authentication for Symfony applications 🔐

scheb/2fa

This bundle provides two-factor authentication for your Symfony application.

ℹ️ The repository contains bundle versions ≥ 5, which are compatible with Symfony 4.4 or later. The older (unsupported) versions are located in the scheb/two-factor-bundle repository.

---

The bundle is split into sub-packages, so you can choose the exact feature set you need and keep installed dependencies to a minimum.

Core features are provided by scheb/2fa-bundle:

• Interface for custom two-factor authentication methods
• Trusted IPs
• Multi-factor authentication (more than 2 steps)
• CSRF protection
• Whitelisted routes (accessible during two-factor authentication)
• Fully customizable conditions when to perform two-factor authentication
• Future proof: Supports the authenticator-based security system, which will replace the current system in Symfony 6

Additional features:

• Trusted devices (once passed, no more two-factor authentication on that device) (scheb/2fa-trusted-device)
• Single-use backup codes for when you don't have access to the second factor device (scheb/2fa-backup-code)
• QR codes to scan with your mobile device

Two-factor authentication methods:

• TOTP authentication (scheb/2fa-totp)
• Google Authenticator (scheb/2fa-google-authenticator)
• Authentication code via email (scheb/2fa-email)

Documentation

Detailed documentation of all features can be found on the Symfony Bundles Documentation website.
