The Credential Management API

The Credential Management API is a standards-based browser API that provides a programmatic interface between the site and the browser for seamless sign-in across devices.

The Credential Management API:

  • Removes friction from sign-in flows - Users can be automatically signed back into a site even if their session has expired or they saved credentials on another device.
  • Allows one tap sign in with account chooser - Users can choose an account in a native account chooser.
  • Stores credentials - Your application can store either a username and password combination or even federated account details. These credentials can be synced across devices by the browser.

Before using the Credential Management API, first check if PasswordCredential or FederatedCredential is supported.

if (window.PasswordCredential || window.FederatedCredential) {
  // Call navigator.credentials.get() to retrieve stored
  // PasswordCredentials or FederatedCredentials.

Sign in user

To sign in the user, retrieve the credentials from the browser's password manager and use them to log in the user.

For example:

  1. When a user lands on your site and they are not signed in, call navigator.credentials.get().
  2. Use the retrieved credentials to sign in the user.
  3. Update the UI to indicate the user has been signed in.

Save or update user credentials

If the user signed in with a federated identity provider such as Google Sign-In, Facebook, GitHub:

  1. After the user successfully signs in or creates an account, create the FederatedCredential with the user's email address as the ID and specify the identity provider with FederatedCredentials.provider.
  2. Save the credential object using

If the user signed in with a username and password:

  1. After the user successfully signs in or creates an account, create the PasswordCredential with the user ID and the password.
  2. Save the credential object using

Sign out

When the user signs out, call navigator.credentials.preventSilentAccess() to prevent the user from being automatically signed back in.

Disabling auto-sign-in also enables users to switch between accounts easily, for example, between work and personal accounts, or between accounts on shared devices, without having to re-enter their sign-in information.
