# Proxy User Overview
Our proxy authentication system is quite complex as it has to allow for multi-user management across different service on a single account as well as traffic usage attribution and supporting proxy authentication methods including username/pass and IP: Authorization.
There are three main objects the API works with for conducting proxy user management, they are:
```
ProxyUser
IpAuthorization --> Accessed through the ProxyUser Routes
Service
```
ProxyUsers can be created and given IP Authorizations then either allowed to acess all services on the account or restricted to certain services. There can be many proxy users on an account and many IP Authorizations.
The API controls write operations to the authentication system and the proxy network then reads the database and allows ProxyUsers to access their respective allowed services / proxies.
{% hint style="info" %}
Every account has a default ProxyUser which can not be deleted and by default has access to all services on the account.
{% endhint %}
