3D Secure or SCA authentication fails

Why did my 3D Secure check fail?

3D Secure, also called Strong Customer Authentication (SCA), is a step your bank adds to card payments. It might ask you to approve in a banking app, type a one-time code or use a fingerprint or face scan. If that step is skipped, times out or is rejected, the payment does not go through. Tapmy and the creator cannot see or approve the challenge.

Try this, in order:

1. Open the real checkout. Start from the creator's Tapmy store or the link in your receipt email. Do not pay through a screenshot, a forwarded payment frame or an unknown message link.
2. Finish the bank prompt. Use the phone or app your bank expects. Never read your code out to anyone.
3. Wait for the page to return. Closing the bank window early, or switching devices halfway, leaves the attempt unfinished.
4. Check before you pay again. Look in your bank app or email for a pending or completed charge. A browser error alone does not tell you the final result, and Stripe holds the payment status.
5. Retry once. If nothing was charged, try again in a current browser with pop-ups allowed. If the same challenge keeps failing, use another card or call the bank.

Who controls what

Your bank decides whether you are authenticated. Stripe records whether the payment succeeded, failed or still needs authentication. Tapmy can check whether checkout handled the result correctly.

What a good result looks like

• The bank check ends with a clear pass or fail.
• A pass produces exactly one payment and one matching order.
• A fail creates no access and no duplicate charge.

Common problems

• The bank window never opens. Allow pop-ups and redirects, leave the in-app browser (Instagram, TikTok and similar) for Safari or Chrome, and check your connection. Some banks need a second device.
• The check passes but checkout shows an error. Save the payment reference and check the charge status before retrying.
• No code arrives. Only your bank can fix or change how it contacts you.
• The page goes blank or loops. Try a different browser, note the time, and tell support.

What to note for support

Write down the checkout URL, amount and currency, buyer email, browser and device, start and return times, the exact message, and redacted order or payment references. Do not screenshot a screen that shows codes, phone numbers or bank details.

Next steps

If the charge completed, confirm access to what you bought. If it failed, see the card decline guide and ask your issuer if needed. Still stuck? Contact Tapmy Support with the store URL, buyer email, approximate time and time zone, amount, and safe references. Never send passwords, one-time codes, full card numbers, bank logins, ID documents or secret keys.
