Users don't need to remember which Google Account they selected during their last visit, decreasing the chances of unnecessary duplicate accounts being created on your platform.</p> <p>Automatic sign-in is intended to complement our Sign in with Google button and One Tap dialogs. It is designed to be used across your entire site, with manual sign-up or switching accounts occurring only after the user has first signed-out of your site.</p> <p>For Automatic sign-in to occur the following conditions are required:</p> <ul> <li>users must first be signed-in to their Google Account, and</li> <li>previously granted consent to share their account profile with your app, and</li> <li>when using FedCM, made only a single sign-in attempt in the last 10 minutes. One Tap is displayed when repeated sign-in attempts occur during this window.</li> <li>when using FedCM, Chrome requires users to reconfirm that they want to sign in to the website with Google Account in each Chrome instance even if the user approved the website prior to the FedCM rollout. This change may affect conversion rate on your existing site using One Tap. In Chrome M121 update, <a href="/identity/gsi/web/reference/release-notes#2023-12-21">Auto Sign-in improvement</a> mitigates conversion rate drop issue.</li> </ul> <p>For pages where Automatic sign-in is enabled and if these conditions are met the user's ID token credential is automatically returned without any user interaction. If these conditions are not met, and even if Automatic sign-in is enabled on the page, the user defaults to the One Tap flow for sign-in or consent. If a user has multiple Google Accounts and visits your site they are required to first sign-in to a single Google Account and to have provided consent for that account.</p> <p>You may measure Automatic sign-in success rate using the <code translate="no" dir="ltr">auto</code> value in the <a href="/identity/gsi/web/reference/js-reference#select_by">select_by</a> field of the returned credential object.</p> <p>To enable automatic sign-in, add <code translate="no" dir="ltr">data-auto_select="true"</code> to your code, as shown in the following snippet:</p> <pre class="prettyprint lang-html" translate="no" dir="ltr"><code translate="no" dir="ltr"><div id="g_id_onload" data-client_id="<var translate="no">YOUR_GOOGLE_CLIENT_ID</var>" data-login_uri="<var translate="no">https://your.domain/your_login_endpoint</var>" data-auto_select="true"> </div> </code></pre><aside class="note"><strong>Note:</strong><span> The <a href="/identity/gsi/web/guides/features#upgraded_ux_on_itp_browsers">upgraded One Tap UX for ITP browsers</a> doesn't support auto sign-in.</span></aside> <h2 id="sign-out" data-text="Sign out" tabindex="-1">Sign out</h2> <p>When a user signs out of your website, they can be directed to a page where a Google One Tap prompt is automatically displayed.

For example, <code translate="no" dir="ltr">logged_out=1</code>. When rendering One Tap by JavaScript API, check that URL parameter and disable auto sign-in when present.</li> </ul> <aside class="warning"><strong>Warning:</strong><span> The term 'sign out' here refers to temporarily disabling One Tap Automatic sign-in for one day.
