# Authorization

## Ash Policy Authorizer

Generally speaking, you will want to use `Ash.Policy.Authorizer` to authorize access to your resources.

At one point, it was a separate package but it is now built directly into Ash.

For usage, see the policies guide.

Implementing a custom authorizer is pretty complex. Instead of writing a guide, it would be best to just have some discussions if/when someone thinks that they need one. Make an issue and we'll talk it over.
