Secure credentials in subflow

I want to include an e-mail node in a subflow and allow the credentials to be configurable via subflow env vars. However I obviously don't want the password appearing as plain text in the flows file. Is there a solution to this problem?

Could node-red-contrib-credentials help?

The ability to identify a subflow property as a credential-type (and thus store its value in the credential store) is in the dev branch and will be in 1.1.0.

I don't think so. I want to be able to configure the email node password in the subflow instance properties, I don't think the credentials node will help with that.

Excellent, thanks.

Any idea of some sort of vague idea when that might be released? Weeks? Months?

Would this allow to move config-node selection from nodes to the subflow configuration?
