FedCM delegation flow
In this page, you can experience and learn FedCM and its "delegation flow". With
FedCM delegation flow, you can sign up to the website with a verified email
address.
*The SD JWT is not verified at the moment. The resulting account is static to be
`me@sgo.to` with name 'Sam Goto'.*
## Prerequisites
* Chrome desktop 137 or later with the following flags:
* "FedCM with delegation support" flag: `chrome://flags/#fedcm-delegation`
* "FedCmWithoutWellKnownEnforcement" flag: `chrome://flags/#fedcm-without-well-known-enforcement`
* "FedCmMultiIdP" flag: `chrome://flags/#fedcm-multi-idp`
* "FedCM with IdP Registration support" flag: `chrome://flags/#fedcm-idp-registration`
* "FedCMAutofill" flag: `chrome://flags/#fedcm-autofill`

## How to use
Just put your cursor on the input field. You should see `me@sgo.to` acount in
the autofill suggestion. It may take a few seconds for the account to show up.
By clicking on it, you can sign up to the website using SD JWT that contains a
verified email address. This means the website doesn't have to send an email to
the registered email address, the user doesn't have to open it and click a link
in the email, to verify the email address.
## How to develop
This feature is still under development and details are to be determined, but it
will be built upon the foundation of FedCM.
