<p>{{SeeCompatTable}}{{APIRef("Credential Management API")}}</p>
<p><a href="/en-US/docs/Web/API/Credential_Management_API">Credential Management API</a> 的 <strong><code>CredentialsContainer</code></strong> 接口提供了请求 credentials 和通知用户代理（当成功登陆或登出事件发生时）的方法。可通过 <code>Navigator.credentials </code>获得该接口。</p>
<h2 id="属性">属性</h2>
<p>None.</p>
<h3 id="事件">事件</h3>
<p>None.</p>
<p> </p>
<p>返回一个带有处理值 <code><a href="https://w3c.github.io/webappsec-credential-management/#credential" id="ref-for-credential-34">Credential</a></code>（若它能够使用提供的选项创建的话）的 <code><a href="https://heycam.github.io/webidl/#idl-promise">Promise</a></code> ，或返回 <code>null</code>（若不能创建 <code><a href="https://w3c.github.io/webappsec-credential-management/#credential" id="ref-for-credential-35">Credential</a></code>）。在特殊情况下，返回的 <code><a href="https://heycam.github.io/webidl/#idl-promise">Promise</a></code> 对象可能 reject。</p>
<h2 id="方法">方法</h2>
<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>
