# Http basic authentication Your [satis](handling-private-packages-with-satis.md) server could be secured with http basic authentication. In order to allow your project to have access to these packages you will have to tell composer how to authenticate with your credentials. The most simple way to provide your credentials is providing your set of credentials inline with the repository specification such as: { "repositories": [ { "type": "composer", "url": "http://extremely:secret@repo.example.org" } ] } This will basically teach composer how to authenticate automatically when reading packages from the provided composer repository. This does not work for everybody especially when you don't want to hard code your credentials into your composer.json. There is a second way to provide these details and is via interaction. If you don't provide the authentication credentials composer will prompt you upon connection to enter the username and password. There is yet another way to provide these details and is via a file `auth.json` inside your `COMPOSER_HOME` which looks something like `/Users/username/.composer/auth.json` { "basic-auth": [ "repo.example1.org": { "username": "my-username1", "password": "my-secret-password1" }, "repo.example2.org": { "username": "my-username2", "password": "my-secret-password2" } ] } This then will provide http basic authentication for two domains serving packages with two different sets of credentials.
