How to create credentials for Docker Hub?
You can generate an access token for docker hub by going here:

https://hub.docker.com/settings/security

And creating a new access token.

It's essentially the same process for organisational access tokens or for personal access tokens IIRC.

Once you have generated the access token you can literally just use that token instead of the password for most docker hub operations (ie. docker login --username $user --password $token)
