Is there any way to use ktor's authentication with a token provided in a query parameter instead of a header?

For the bearer provider, you can use the `authHeader` method to configure the token's source. Here is an example:
```install(Authentication) {
    bearer {
        authHeader { 
            val auth = it.request.queryParameters["auth"] ?: throw BadRequestException("No auth query parameter given")
            parseAuthorizationHeader(auth)
        }
    }
}```

Thanks, that's perfect! Just funny that it's called `authHeader`...?

Since there we're really setting the auth source, shouldn't it be `authSource { }`?

Not exactly, since the source also has to be parsed.

As a result to that parse function, I get the token in the authScheme of the HttpHeader... is that what's supposed to happen?

It seems to skip the `authenticate { }` block in `bearer {  }` too...

```install(Authentication) {
    bearer {
        authHeader { 
            val auth = it.request.queryParameters["auth"] ?: throw BadRequestException("No auth query parameter given")
            parseAuthorizationHeader("Bearer " + auth)
        }
    }
}```
this works... I need to add `Bearer ` to the auth token.

It depends on the format of the value in the header.
