Risks
Interoperability and Compatibility

Zero compatibility risk (new API)

Interoperability risk not yet known, currently working on getting formal
signals

Gecko: No signal

WebKit: No signal

Web developers: No signals

Other signals: This proposal has been presented in TPAC 2022/2021 and the
last two BlinkOn sessions. This API was initially incubated at the WICG and
is now being developed within the FedID CG <https://github.com/fedidcg>
with attendance of identity providers, browser vendors and standards
experts.

Goals for experimentation

Learn about demand, requirements, ergonomics and deployment viability.

Ongoing technical constraints

   -

   Currently, limited Android only implementation
   -

   Currently, only ID tokens provided, no access or refresh tokens
   -

   Currently, limited session management functionality (only front-channel
   logout)


Debuggability

Basic devtools integration supported (tracking bug
<https://bugs.chromium.org/p/chromium/issues/detail?id=1291653>, HOWTO
<https://github.com/fedidcg/FedCM/blob/main/explainer/HOWTO.md>). More to
come as we learn.

Will this feature be supported on all six Blink platforms (Windows, Mac,
Linux, Chrome OS, Android, and Android WebView)?

At I2S, we expect the feature to be available on all platforms (Windows,
Mac, Linux, ChromeOS and Android) but WebView. The current implementation
is currently only supported on Android, with Desktop
(Windows/Mac/Linux/ChromeOS) coming next.

Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md>
?

Yes
