Admins can configure the system to send email notifications for specific security-related activities. *** ### Available Security Notifications Choose for users to receive notifications for the following security-related events: **Access from a Different Geographic Location** An email is sent to only the user when their geographical location changes since their last login. *** **Multiple Failed Password Attempts** An email is sent to the user and all network admins when a user exceeds the allowed number of failed login attempts as set in the [Failed Authentication Attempt Policy](https://guides.mangoapps.com/admin-guide/security/password-settings#failed-authentication-attempt-policy). *** **Unauthorized Access Attempt** An email is sent to all network admins when a user attempts to access content they do not have permission for. Example: A user tries to open a file shared via a link but is not a member of the respective team. *** **Unauthorized Attempt to Access an Invalid URL** An email is sent to all network admins when a user tries to access a non-existent or invalid URL. Example: A user attempts to open a post or file that has been deleted. *** **Unauthorized Attempt to Access the Admin Portal** An email is sent to all network admins when a network or guest user tries to access the admin portal without proper authorization. *** **Unauthorized Attempt to Access from Outside Valid IP Range** An email is sent to all network admins when a user tries to access the domain from an IP address outside the defined IP range for browser access. Example: A user attempts access from IP 77.111.247.13, but the allowed range is 111.123.168.1 to 111.123.168.999.
