Credential Management API
The Credential Management API lets a website store and retrieve password, public key, and federated credentials. These capabilities allow users to sign in without typing passwords, see the federated account they used to sign in to a site, and resume a session without the explicit sign-in flow of an expired session.
This API lets websites interact with a user agent's password system directly 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.
To address these problems, the Credential Management API provides ways for a website to store and retrieve different types of credentials. This gives 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.
This API is restricted to top-level contexts. Calls to
store() within an
<iframe> element will resolve without effect.
Later version of the spec allow credentials to be retrieved from a different subdomain. For example, a password stored in
login.example.com may be used to log in to
www.example.com. To take advantage of this, a password must be explicitly stored by calling
CredentialsContainer.store(). This is sometimes referred to as public suffix list (PSL) matching; however the spec only recommends using PSL to determine the effective scope of a credential. It does not require it. Hence browsers may vary in their implementation.
- Provides information about an entity as a prerequisite to a trust decision.
- 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
- 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.
- Provides information about a username/password pair.
- Provides a credential for logging in using a more secure system based on asymmetric cryptography instead of a password.
