"Remember Me" option at checkout
What does the “Remember Me” checkbox on my checkout page do? How do I unenroll in “Remember Me”?
“Remember Me” allows customers to save their payment information for future use using a mobile verification process, not unlike two-step verification. Currently, “Remember Me” is only available for merchants who collect payments using Stripe Checkout.
If a customer selects “Remember Me” while checking out and enters their phone number, they will receive a confirmation code sent via SMS to their mobile device. Once they’ve confirmed setup using the code, they can make payments quickly using the same mobile verification process in the future.
