Checkpoint
Are you a returning customer?
A device we recognize passes instantly. Otherwise, prove it the slow way.
Opted in ✓ Safari will now ask — once — whether this site may see your device age.
Tap SPEED CAPTCHA and choose Allow.
On Safari: the very first tap takes you to a one-time opt-in page. After that, each site
asks Safari's permission once and remembers it — later visits just show your age.
Nothing to recognize
This browser isn't sharing the device cookie with this site (third-party cookies are
blocked), so SPEED CAPTCHA has nothing to read. Use Slow Captcha instead.
Safari didn't grant access
You opted in, but Safari's permission was declined or dismissed. Tap
SPEED CAPTCHA again and choose Allow. If it keeps failing,
make sure Settings › Safari › Block All Cookies is off.
Slow Captcha
The usual way: prove you're human by hand. This is what a good customer without a known
device gets. Compare the time with SPEED CAPTCHA.
