Send a sign-in code
Emails a six-digit code to the address a buyer typed, for them to type back with Sign in with the code. The code works for 10 minutes, five tries.
The answer is the same for any address, and a code is only mailed to an address that has orders at the store, so this cannot be used to find out who has bought there. One address is sent a code a minute at most, five an hour and ten a day: past that the answer is code_cooldown with resendIn, the seconds to wait. A store sends 60 codes an hour at most, and past that, or on a busy hour for the whole platform, the answer is store_busy.
Call it from the buyer’s own device. It is counted for the address that asks, 10 an hour, so a server asking for every buyer would run out at once.
