The Credential Management API enables a website to create, store, and retrieve credentials. A credential is an item which enables a system to make an authentication decision: for example, to decide whether to sign a user into an account. We can think of it as a piece of evidence that a user presents to a website to demonstrate that they really are the person they are claiming to be.
Concepts and usageThe central interface is the CredentialsContainer, which is accessed through the navigator.credentials property and provides three main functions:
create(): create a new credential.store(): store a new credential locally.get(): retrieve a credential, which can then be used to log a user in.The API supports four different types of credential, which are all represented as subclasses of Credential:
The guide page Credential types gives an overview of the different credential types and how they are used.
InterfacesCredential
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 interface 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.
Navigator.credentials Read only
Returns the CredentialsContainer interface which exposes methods to request credentials and notify the user agent when interesting events occur such as successful sign in or sign out.
