How to recover authentication_required failed payments in Stripe
3D Secure / SCA declines need the customer to act — no retry will fix them. The recovery email that gets authentication completed, and why these cases are urgent.
What authentication required means
The customer's bank demands strong authentication (3D Secure / SCA) before approving the charge. The payment is stuck until the customer completes a verification step — usually one tap in their banking app.
Why it happens
- European cards under PSD2/SCA rules require authentication for many recurring charges.
- The bank's fraud model flagged this particular charge for verification.
- An off-session subscription charge can't complete authentication without the customer present.
What Stripe does on its own
Stripe marks the invoice as requiring action and can email a hosted link, but silent retries cannot satisfy an authentication challenge. The customer must click through and approve.
The recovery playbook
- Send the hosted invoice link with a clear, calm explanation: their bank needs a quick confirmation, it takes under a minute, nothing is wrong with their card.
- Treat these as time-critical — authentication requests expire, and each re-attempt restarts the friction.
- Avoid alarming language; 'your payment failed' reads scarier than 'your bank wants a quick confirmation' and produces worse completion rates.
- If the same customer hits authentication_required repeatedly, suggest they re-enter the card so Stripe can request an off-session exemption going forward.
Recovery is almost entirely a function of how fast and how clearly you ask — the customer's intent to pay is nearly always intact.
The email to send
This is the exact template MRRdue's recovery assistant suggests for authentication_required cases — copy it, swap the details, and send it from your own address.
Subject: Please confirm your subscription payment
Hi Alex, Stripe is asking for confirmation before it can complete your $49.00 subscription payment. You can use Stripe's secure payment page to update the payment method and retry the invoice: https://invoice.stripe.com/i/… This usually takes less than a minute. Thanks, Your SaaS
