I install the module and go to add a username/password key. At the bottom of the page I get a cryptic form element "Key value" without a description. Maybe this is obvious to some people what the expected value is, but I don't think it is obvious.
Is the format "username=value"? Is it "username|value"? Is it "username value"? Are the values comma separated? Line break separated? Is this even used for a username and password at the same time? The documentation pages aren't clear on this either.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
