<dl>
 <dt>{{domxref("CredentialsContainer.create()")}}</dt>
 <dd>Returns a {{jsxref("Promise")}} that resolves with a new {{domxref("Credential")}} instance based on the provided options, or <code>null</code> of no <code>Credential</code> object can be created.</dd>
 <dt>{{domxref("CredentialsContainer.get()")}}</dt>
 <dd>Returns a {{jsxref("Promise")}} that resolves with the {{domxref("Credential")}} instance that matches the provided parameters.</dd>
 <dt>{{domxref("CredentialsContainer.preventSilentAccess()")}}</dt>
 <dd>Sets a flag that specifies whether automatic log in is allowed for future visits to the current origin, then returns an empty {{jsxref("Promise")}}. For example, you might call this, after a user signs out of a website to ensure that he/she isn't automatically signed in on the next site visit. Earlier versions of the spec called this method <code>requireUserMediation()</code>. See {{anch("Browser compatibility")}} for support details.</dd>
 <dt>{{domxref("CredentialsContainer.store()")}}</dt>
 <dd>Stores a set of credentials for a user, inside a provided {{domxref("Credential")}} instance and returns that instance in a {{jsxref("Promise")}}.</dd>
