System Requirements

Before installing OneTap Login for WooCommerce, verify that your server and website meet all requirements.

Server Requirements

Requirement	Minimum	Recommended
PHP Version	7.4	8.0+
WordPress Version	5.8	6.4+
WooCommerce Version	5.0 (optional)	8.0+
MySQL Version	5.6	8.0+
Memory Limit	64MB	256MB+

How to Check Your PHP Version

1. Go to Tools > Site Health in your WordPress admin
2. Click the Info tab
3. Expand Server section
4. Look for "PHP version"

Alternatively, create a file called phpinfo.php with:

<?php phpinfo(); ?>

Delete After Checking

Remember to delete phpinfo.php after checking—it exposes sensitive server information.

SSL Certificate (HTTPS) - Required

Google requires HTTPS for all OAuth implementations. Your site must have a valid SSL certificate.

How to verify:

• Your site URL should start with https://
• No browser warnings when visiting your site
• Padlock icon appears in the address bar

HTTP Not Supported

Google will reject authentication requests from non-HTTPS sites. There is no workaround—SSL is mandatory.

Browser Compatibility

OneTap Login supports all modern browsers:

Browser	Minimum Version	One Tap Support
Chrome	90+	Full
Firefox	88+	Full
Safari	14+	Full
Edge	90+	Full
Opera	76+	Full
IE 11	-	Not Supported

Mobile Browsers

Browser	Support
Chrome for Android	Full
Safari for iOS	Full

Google Account Requirements

To set up the plugin, you need:

1. Google Account - Any Google account (personal or Workspace)
2. Google Cloud Console Access - Free to create
3. OAuth Consent Screen - Configuration required (no verification needed for testing)

No Google Workspace Required

You don't need Google Workspace or a paid Google account. A free Gmail account works perfectly for creating OAuth credentials.

• Button appears on: My Account, Checkout, Cart
• Default role: customer
• User creation via: wc_create_new_customer()
• Post-login redirect: WooCommerce My Account page
