# Two-Factor WordPress Plugins

**Two-Factor WordPress Plugins**

Use the “Two-Factor Options” section under “Users” → “Your Profile” to enable and configure one or multiple two-factor authentication providers for your account:

- Email codes
- Time-Based One-Time Passwords (TOTP)
- FIDO Universal 2nd Factor (U2F)
- Backup Codes
- Dummy Method (only for testing purposes)

## ACTIONS & FILTERS:

Here is a list of action and filter hooks provided by the plugin:

- **two_factor_providers** filter overrides the available two-factor providers, such as email and time-based one-time passwords. Array values are PHP class names of the two-factor providers.
- **two_factor_enabled_providers_for_user** filter overrides the list of two-factor providers enabled for a user. The first argument is an array of enabled provider class names as values, the second argument is the user ID.
- **two_factor_user_authenticated** action, which receives the logged-in `WP_User` object as the first argument for determining the logged-in user right after the authentication workflow.
- **two_factor_token_ttl** filter overrides the time interval in seconds that an email token is considered after generation. Accepts the time in seconds as the first argument and the ID of the `WP_User` object being authenticated.
