If you are using the legacy version of Stripe Checkout, the "Remember Me" checkbox allows customers to save their payment information during their checkout process for future payments using mobile verification.
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 have confirmed setup using the code, they can make payments quickly using the same mobile verification process in the future.
"Remember Me" is currently only available for merchants who collect payments using legacy Stripe Checkout.
"Remember Me" is not supported in the new Checkout.
If you are a customer and no longer want your information saved, or if you are a merchant who received a request from a customer to delete their information from the "Remember Me" service, contact Stripe Support.
