Credential

A credential is an object which enables a system to make an authentication decision: for example, to decide whether to sign a user into an account. In web security, types of credential include:

  • a password
  • biometric data
  • a token entered from a one-time SMS code
  • the key used to make authentication assertions in a public-key system such as Web Authentication

The Credential Management API enables developers to create, store, and retrieve various types of credential.
