Announcing Shield: an Official Authentication library

Do you still need to install via composer for the latest CI4?
Are there CI docs or on github?

Thanks

Yes, Shield is required to be intended through Composer. You could probably do a manual install by downloading it and manually adding the CodeIgniter\Shield namespace to app/Config/Autoload, but it hasn't been tested and there's no support for that.

On a fresh install of ci4, it fails.

composer require codeigniter4/shield
Could not find a version of package codeigniter4/shield matching your minim
um-stability (stable). Require it with an explicit version constraint allow
ing its desired stability.
