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

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

The CredentialsContainer interface of the the Credential Management API exposes methods to request credentials and notify the user agent when events such as successful sign in or sign out happen. This interface is accessible from Navigator.credentials.



Event handlers



returns a Promise which resolves with a Credential if one can be created using the options provided, or null if no Credential can be created. In exceptional circumstances, the Promise may reject


CredentialsContainer.create()Secure context
Returns a Promise that resolves with a new Credential instance based on the provided options, or null of no Credential object can be created.
CredentialsContainer.get()Secure context
Returns a Promise that resolves with the Credential instance that matches the provided parameters.
CredentialsContainer.preventSilentAccess()Secure context
Sets a flag that specifies whether automatic log in is allowed for future visits to the current origin, then returns an empty Promise. For example, you might call this, after a user signs out of a website to ensure that he/she isn't automatically signed in on the next site visit. Earlier versions of the spec called this method requireUserMediation(). See Browser compatibility for support details.
CredentialsContainer.store()Secure context
Stores a set of credentials for a user, inside a provided Credential instance and returns that instance in a Promise.
