You don't need to register an SSH key to download a public repo I thought

Not an SSH key, but you do need an access token:

...but not to download. You can clone a repo and download release artifacts without a PAT. That's only necessary for interacting with the API for actions that need authentication, which would be anything involving mutating a repository.

[timdorr]

Yes, you need one to download. Note that you'll get an auth prompt for this Registry API URL:

https://docker.pkg.github.com/v2/test/test/test/tags/list

> "code": "UNAUTHORIZED", "message": "GitHub Docker Registry needs login"

Using the GitHub Docker Registry requires auth, even just for downloads.

GitHub Packages is different from GitHub Releases (and their artifacts) or cloning repos.

Yes, you do.

GitHub access tokens are a bit of a nightmare since you can't limit the permissions for a token. Only workaround I've found is to create another GitHub user for an access token and restrict that user's access.
