# How to use MerciApp Windows with a system proxy?

Your company may be equipped with a proxy that requires authentication using a username and password assigned to you.

# Configuration

When launched, if a proxy is detected, MerciApp Windows will ask you to enter your credentials in the window below. Once the credentials have been entered, the application will perform a connection test; if the credentials are valid, it will launch normally, and you will not have to enter them again.
