# IP Access Control

To further enhance your security, MessageFlow allows you to restrict access to your account based on IP addresses. This feature acts as an additional layer of protection, ensuring that login attempts to the panel, API, or SMTP can only be made from trusted locations that you define, such as your office network. By creating a whitelist of approved IP addresses, you can effectively block access from any other location, providing you with greater control and peace of mind.
