 # Authentication
 
-When you have a multiplayer game,  often you need to store information about your player for later games, keep game stats or communicate with your friends. For all these use cases,  you often need a way to uniquely identify a user. Being able to tell users appart is called authentication.  There are several methods available,  some examples include:

For all these use cases, you often need a way to uniquely identify a user. Being able to tell users apart is called authentication. There are several methods available, some examples include:
 
-* Ask the user for username and password
-* Use a third party oath or openid identity provider, such as facebook, twitter, google
-* Use a third party service such as playfab, gamelift or steam
-* Use the device id,  very popular method in mobile
-* Use Google Play in android
-* Use Game Center in ios
-* Use a web service in your website

-Trying to write a comprehensive authentication framework that cover all these is very complex.  There is no one size fit all, and we would quickly end up with bloated code.

 Here is an example of how to implement simple username/password authentication:
 
-1) Select your NetworkManager gameobject in the unity editor.
-2) In the inspector, under `Spawn Info`, disable `Auto Create Player`
-3) Call `AddPlayer` in your client to pass the credentials. 
-4) Override the `OnServerAddPlayer` method and validate the user's credential.

 ## Warning
 
-By default Mirror uses Telepathy,  which is not encrypted.  The above code sample works,  but if you want to do authentication through Mirror,  we highly recommend you use a transport that supports encryption.
