NavigatorLogin: setStatus() method

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The setStatus() method of the NavigatorLogin interface sets the login status of a federated identity provider (IdP), when called from the IdP's origin. By this, we mean "whether any users are logged into the IdP on the current browser or not". This should be called by the IdP site following a user login or logout.

The browser stores this state for each IdP; the FedCM API API then uses it to reduce the number of requests it makes to the IdP (because it does not need to waste time requesting accounts when there are no users logged in to the IdP). It also mitigates potential timing attacks.

See Update login status using the Login Status API for more information about FedCM login status.





A string representing the login status to set for the IdP. Possible values are:

  • "logged-in": The IdP has at least one user account signed in.
  • "logged-out": All IdP user accounts are currently signed out.

Return value

A Promise that fulfills with undefined.
