Why docker login command saves unencrypted password on my computer?

Question

I've used docker login command and passed my credentials and I got warning WARNING: login credentials saved in /Users/{my_username}/.docker/config.json. I've checked that file and indeed my password is there unencrypted (base64 encoded only).

Why docker saved my password unencrypted? Shouldn't it save it in my key-chain (I am on Mac OS) or instead of saving password just generate some access token or something like that?

Answer 1

This is now solved, and as you suggest, you can save to the keychain (or use other "helpers"). Full details are in the Docker docs: https://docs.docker.com/engine/reference/commandline/login/#credentials-store

For anyone interested in the history and why this wasn't a trivial fix: https://github.com/docker/docker/issues/10318

Answer 2

You can use Credential Store for this purpose. Here is the offical doc from Docker:
