Actions & Filters

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

• The two_factor_providers filter overrides the available two-factor providers, such as email and time-based one-time passwords. The array values are PHP classnames of the two-factor providers.
• The 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 classnames 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.
• The two_factor_token_ttl filter overrides the time interval in seconds that an email token is considered after generation. It accepts the time in seconds as the first argument and the ID of the WP_User object being authenticated.
