This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The requireUserMediation() method of the CredentialsContainer interface returns an empty Promise after requiring user mediation for credentials returned form a particular origin. Mediation is a per origin indication stored in the browser that the user doesn't want automatic sign-in.

For example, you might call this after a user signs out of a website to ensure that said user isn't automatically signed in on the next site visit.


CredentialsContainer.requireUserMediation().then(function() { ... })




An empty Promise.
