Supports "mediation requirements" to provide streamlined re-authentication UX for users who have created federated accounts on websites with FedCM API.
Firefox: Positive — We have been actively working with Firefox to standardize this API. In general we are aligned on the feature itself. e.g. auto re-authentication can provide streamlined UX without reducing privacy. The current API shape matches with what Firefox has in mind and we will work out more details: https://github.com/fedidcg/FedCM/issues/429#issuecomment-1426162273
Safari: Closed Without a Position — No signal for “auto re-authn” yet. Positive for the general FedCM API.
