You can restrict access to allow users to login only from a set of IP addresses. This feature will come in handy if you want to allow users to access the CRM only from the office and not from anywhere else.
IP based restriction is common for all users. It is not possible to restrict access to some users, and not others. Once the IP address restriction is enabled, only users accessing from those addresses will be able to login. Even access from the Mobile app is restricted to these IP addresses.
To enable IP based restriction, please send the list of IP addresses to email@example.com.
