Google reCAPTCHA is an invisible security feature that prevents spam submissions in forms, newsletters, promotional pop-ups, and product waitlists. Most Squarespace sites use reCAPTCHA v3, which works invisibly without user interaction, except for homepage forms which use reCAPTCHA v2.

Enabling reCAPTCHA

Form Blocks:

1. Click Edit > pencil icon on form block
2. Go to Storage tab
3. Click Google reCAPTCHA
4. Enable "Activate Google reCAPTCHA"

Newsletter Blocks:

• Enabled by default
• To re-enable: Follow same steps as form blocks
• Requires linked Squarespace storage

Promotional Pop-ups:

1. Open pop-up panel > Action
2. Select "Subscribe to a newsletter"
3. Click Validation > Activate reCAPTCHA

Product Waitlist:

• Automatically enabled, no action required

Homepage Forms (Version 7.0)

To set up reCAPTCHA v2:

1. Open Developer Tools > External API Keys
2. Get Google reCAPTCHA API keys
3. Choose reCAPTCHA V2 with "I'm not a robot" checkbox
4. Add all domains (yoursite.squarespace.com and custom domains)
5. Copy and paste site key and secret key to Squarespace

Common Issues

• Invalid domain error: Add all domains in Google reCAPTCHA settings
• Invalid key type: Use reCAPTCHA V2, not V3
• Submission errors: Check for extra text in Secret Key field
• iOS scrolling issue: Known limitation between iOS and Google

Remember to update reCAPTCHA settings when changing domains, and allow up to 30 minutes for changes to take effect.
