+## Unreleased

+### Added
+
+* The `JuliaHub.authenticate` function now supports a two-argument form, where you can pass the JuliaHub token in directly, bypassing interactive authentication. (??)

+Authenticates with a JuliaHub server, returning a [`JuliaHub.Authentication`](@ref) object and
+setting the global authentication session (see [`JuliaHub.current_authentication`](@ref)).
+May throw an [`AuthenticationError`](@ref) if the authentication fails (e.g. expired token).
+
+The zero- and one-argument methods will attempt to read the token from the current Julia depot.
+If a valid authentication token does not exist in the Julia depot, a new token is acquired via an
+interactive browser based prompt. By default, it attemps to connect to the currently configured Julia
+package server URL (configured e.g. via the `JULIA_PKG_SERVER` environment variable), but this
+can be overridden by passing the `server` argument.
+
+The two-argument method can be used when you do not want to read the token from the `auth.toml`
+file (e.g. when using a long-term token via an environment variable). In this case, you also have
+to explicitly set the server URL and `JULIA_PKG_SERVER` is ignored.

 The interactive prompts tries to authenticate for a maximum of `maxcount` times.
 If `force` is set to `true`, an existing authentication token is first deleted. This can be
 useful when the existing authentication token is causing the authentication to fail.

 `hook` can be set to a function taking a single string-type argument, and will be passed the

 behavior coming from [PkgAuthentication](https://github.com/JuliaComputing/PkgAuthentication.jl).
