Understand One Tap User Experience

Shows a dialog to prevent unintended clicks

One Tap now comes with different security measures to enforce the integrity of the dialog box, but some browsers don't support these capabilities. Unsupported browsers include non-Chromium-based ones or those before v75. In these cases, or if the dialog is covered with other content, a pop-up window is displayed that requests the user's consent to create an account.

Globally opt out

Users can opt out of One Tap if they disable the Google Account sign-in prompts flag in the Apps with access to your account page. The opted-out sessions aren't shown in One Tap. If all Google sessions are opted out, One Tap doesn't display.

Exponential cooldown

If the user closes the One Tap prompt manually, the One Tap prompt is suppressed. A user closes One Tap when they tap Close in the top-right corner of the prompt. One Tap won't display in the same browser or the last website visited for a period of time.

The following exponential time periods are used for cooldowns:

Consecutive times closed Time period that One Tap is disabled
1 Two hours
2 One day
3 One week
4+ Four weeks

The cooldown status resets after a successful One Tap sign-in.

Auto-dismissal on mobile browsers

On mobile browsers, Google One Tap closes automatically after a short time period unless the user directly interacts with the One Tap UI.

Currently, the threshold for auto-dismissal is 90 seconds. We might adjust it in the future.

Upgraded UX on ITP browsers

Due to Intelligent Tracking Prevention (ITP), the normal One Tap UX doesn't work on Chrome on iOS and Safari. An upgraded One Tap UX is provided instead, which requires you to enable it explicitly by setting the data-itp_support attribute.

The upgraded One Tap UX on ITP browsers will start with a warm welcome page as below. Once the user chooses to continue, a popup window will be opened. The UX in the popup window is quite similar to normal One Tap.
