Face Verification Not Working on iPhone? Safari and App Fixes

If the face verification step on an exchange freezes on your iPhone, the problem is almost always technical rather than about your identity. Check that the camera is allowed, make sure the check is running in the official app or in Safari, use a stable connection and even lighting, then try again. If it still fails after that, use another supported device or contact official support with the details listed below.

What “stuck” usually looks like

• The camera preview is black or frozen after you tap start.
• A spinner keeps loading and the check never begins.
• The instructions (“move closer”, “turn your head”, “blink”) repeat without finishing.
• The check finishes, then says “verification failed” and returns to the start.
• You scanned a QR code from your computer and the page on your phone does not open the camera.

Note which of these you see. It points to the likely cause and is useful if you need to contact support.

Step 1: Check camera permission

iPhone permissions are set separately for each app and for Safari.

• In the exchange app: open Settings > Privacy & Security > Camera and make sure the exchange app is switched on in the list.
• In Safari: open Settings > Apps > Safari > Camera and choose Ask or Allow. Deny blocks the camera for every website. When the page asks for camera access, tap Allow.
• For one website only: in Safari, open the page menu, tap Website Settings and check the Camera setting for that site.
• Screen Time: if Screen Time content restrictions are on, check that the camera is not restricted.

After changing permissions, fully close the app or the Safari tab and start the verification again.

Step 2: Make sure the check opened in the right place

Liveness checks often fail inside “in-app browsers”, which are the pages that open when you tap a link inside a messaging or social app. Those browsers may not get camera access. Start verification from the official exchange app, or open the website directly in Safari by typing the address yourself. If you scanned a QR code from a desktop, make sure it opened in Safari or in the exchange app, not inside another app.

Step 3: Rule out the phone and the connection

• Update the exchange app from the App Store and update iOS if an update is waiting.
• Turn off Low Power Mode during verification and let the phone cool down if it is warm.
• Close screen recording, screen mirroring and apps that draw over the screen.
• Switch between Wi-Fi and mobile data. A connection that drops for a moment can reset the check. If you use a VPN or privacy relay, try without it, since some verification services are sensitive to changing connections.
• Restart the iPhone if the camera does not work in the regular Camera app either.

Step 4: Fix the capture conditions

• Face a window or a soft light source. Avoid strong light behind you.
• Hold the phone at eye level with your whole face centred in the frame and your eyes open.
• Take off hats, masks and glasses, including regular glasses, and turn off any camera filters. Binance’s verification guide asks users to avoid hats, glasses and filters.
• Move slowly and only when the screen tells you to.
• Use a plain background with nobody else in the frame.
• Do not refresh the page, switch to another app or lock the screen until the check finishes. Binance’s guide says not to refresh the browser or quit the app during verification.

If it keeps failing

Some platforms let you complete verification on another device or through the website. If yours does, try the officially supported alternative. Avoid trying dozens of times in a row; repeated failures can lead to a temporary block on further attempts. If you see a message asking you to wait, wait before trying again.

What to note before contacting support

Write down your iPhone model, iOS version, app version (or “Safari”), the time of the last attempt, the exact error message, and which of the symptoms above you saw. Open one ticket through the official support center and keep all follow-ups in the same thread.

What not to do when verification keeps failing

• Do not send selfies, videos or ID photos to anyone in a chat group or by email who says they can “pass” verification for you.
• Do not use another person’s face or a photo of a screen. That turns a technical problem into a fraud review.
• Do not install configuration profiles, “unlock” apps or remote-access tools to get the camera working.

If your ID document is also being rejected, read how to fix KYC document glare and blur, or for other rejection reasons, why KYC verification gets rejected.

Frequently asked questions

Why does face verification work on my friend’s phone but not mine? Usually because of a permission, an older app or iOS version, or a setting such as Low Power Mode on your phone. Go through steps 1 to 3 above. Do not complete your verification using your friend’s face or account.

The camera is black only during verification. What should I check? Check the camera permission for the app or for Safari, close other apps using the camera, and make sure the page did not open inside a messaging app’s browser.

How many times can I retry face verification? It depends on the platform. If you see a message limiting attempts or asking you to wait, follow it rather than trying again immediately.

Can support verify me manually if the camera never works? Some platforms offer alternatives or manual review, but this is their decision. Explain the problem with your device details in one official ticket and ask what options are available.
