I couldn't approve an online payment
Some online payments use 3D Secure, which protects against unauthorised use of your card.
A merchant can choose to request this verification if they want to make sure it’s you making the payment.
You can approve this in two different ways:
- By opening your Monzo app, pressing approve and entering your card's PIN
- By requesting a code via text message (SMS), then entering that code
Some merchants don't allow you to do the first option, so if a payment fails please try again and press "Use SMS" instead 👍
