Credential Management API

Credential management concepts and usage

This API lets websites interact with a user agent’s password system so that websites can deal in a uniform way with site credentials and user agents can provide better assistance with the management of their credentials. For example, user agents have a particularly hard time dealing with federated identity providers or esoteric sign-in mechanisms that use more than just a username and password. To address these problems, the Credential Management API provides ways for a website to store and retrieve different types of password credentials. This give users capabilities such as seeing the federated account they used to sign on to a site, or resuming a session without the explicit sign-in flow of an expired session.

Use with fetch

The init parameter of the fetch event has a property called credentials. In browsers that support the Credential Management API, this property has been enhanced to take a credential object (either FederatedCredential or PasswordCredential).

Interfaces

Credential

Provides information about an entity as a prerequisite to a trust decision.

CredentialsContainer

Exposes methods to request credentials and notify the user agent when interesting events occur such as successful sign in or sign out. This interfaces is accessible from Navigator.credentials.

FederatedCredential

Provides information about credentials from a federated identity provider, which is an entity that a website trusts to correctly authenticate a user, and which provides an API for that purpose. OpenID Connect is an example of such a framework.

PasswordCredential

Provides information about a username/password pair.
