This authentication setting can be turned on or off by request only. Only users accessing the site from permitted IP addresses will receive the email containing this code. To set this up, you will need to provide a list of the IP addresses that you would like to have access to your site. More information about 2FA can be found [here](https://guide.contentcatalyst.com/hc/en-gb/articles/360020424937-user-login-experience?hsLang=en).  **🔔 Note: Enabling 2FA prevents the use of the API** ### Password Age Your site allows you to set how frequently a user needs to change their password on the site.  This setting is a preference called “Maximum user password age”. Details on changing preferences can be found **[here](https://guide.contentcatalyst.com/hc/en-gb/articles/212092226-how-to-set-a-password-expiry-at-user-level?hsLang=en).**  There is also the option to set a one-off password expiry or prompt a user to change their password at log-in. More details about this can be found **[here](https://guide.contentcatalyst.com/hc/en-gb/articles/212092186-how-to-send-users-a-password-reset-code?hsLang=en). ** ### Trusted Domains Your site allows you to restrict which email domains can be used to access the site at an account level. More information on how to do this can be found **[here](https://guide.contentcatalyst.com/hc/en-gb/articles/212092166-trusted-domains?hsLang=en).** ### ReCAPTCHA It is possible to enable a reCAPTCHA widget on your site.
