How saved payment methods work with passwordless login

Saved payment methods are linked to a secure payment account, not directly to a game's player_id.

• The payment account requires an email address and a phone number (SMS) for access.
• Once a card is saved, it can be reused on the current device or on another device after the user logs in through email or SMS verification.
• A saved payment method cannot be accessed simply by knowing or guessing a player_id.

In practice, this means users do not need to re-enter their card details for every purchase as long as they can authenticate into their payment account.
