This bundle provides two-factor authentication for your Symfony application. It comes with the following two-factor authentication methods:

• Google Authenticator
• Email authentication code

Additional features you will like:

• Interface for custom two-factor authentication methods
• Trusted IPs
• Trusted devices (once passed, no more two-factor authentication on that device)
• Single-use backup codes for when you don't have access to the second factor device
• Multi-factor authentication
• CSRF protection
• Whitelisted routes (accessible during two-factor authentication)

composer require scheb/two-factor-bundle

... and follow the installation instructions.

Detailed documentation of all features can be found in the Resources/doc directory.

• Use bundle version 4.x for Symfony 3.4 and 4.x (Recommended version)
• Use bundle version 2.x for Symfony < 3.4
• Use bundle version 1.x for Symfony < 2.6

Before version 3.7 the bundle is vulnerable to a security issue in JWT, which can be exploited by an attacker to generate trusted device cookies on their own, effectively by-passing two-factor authentication.
