This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The credentials property of the Navigator interface returns the CredentialsContainer interface, which exposes methods to request-credentials. The CredentialsContainer interface also notifies the user agent when an interesting event occurs, such as a successful sign-in or sign-out. This interface can be used for feature detection.


var credentialsContainer = navigator.credentials


The CredentialsContainer interface.


if ('credentials' in navigator) {
  navigator.credentials.get({password: true})
  .then(function(creds) {
    //Do something with the credentials.
} else {
  //Handle sign-in the way you did before.
