BCCing public-webapps@, as this proposal started there[1]. It looks like it
might be reasonable to charter the spec work as part of the WebAppSec
WG[2], however, so I'm moving the conversation here for the time being.

Way back in August, I proposed a credential management API. After some
generally positive conversation with folks at Mozilla and other vendors, I
started poking at a prototype in Chrome to help us evaluate whether the API
made any sense. As of some time earlier this week, there's enough in Canary
to start looking at.

If you visit https://credential-manager-api-test.appspot.com/ in Canary
with the '--enable-credential-manager-api' flag set, you can save
credentials via `navigator.credentials.notifySignedIn()` and retrieve them
via `navigator.credentials.request()`. It only supports "local"
credentials, and doesn't do any of the UI song and dance that's still very
much TBD, but it's a nice proof of concept.

Note: Don't do this on any profile with data you care about. The current
implementation just blindly returns the first credential that matches the
origin on which the API is called, without user mediation. That's probably
not something you want to expose to the web in its current state. :)

I'd invite you to take a look at the strawman proposal (
https://mikewest.github.io/credentialmanagement/spec/), and help me decide
whether the API makes any sense. If nothing else, it'll give us something
to talk about at TPAC.
