Username and password authentication is suitable when the client IP changes or when credentials must travel with the connection configuration.

Steps

1. Copy the generated username and password from the dashboard.
2. Enter them in the proxy fields supported by your browser, application, or HTTP client.
3. Avoid URL-encoding mistakes when a credential contains special characters.
4. Rotate exposed credentials and update every dependent client.

Checks and notes

• A 407 response usually means credentials were missing, rejected, or formatted incorrectly.

For account-specific values, use the endpoint, port, credentials, and location shown in your MaskProxy dashboard. Do not publish proxy credentials in screenshots, tickets, or public code repositories.
