You do not need to wait for anybody. SmartPay sends a code to the phone already on your staff record, and you choose a new password yourself.
Type your username or staff number. We will send a code to the phone on your record.
SmartPay cannot send a code at the moment, so one will not reach you.
SMS sending is switched off (Settings, Text messages, Send text messages). Until that is put right, ask whoever manages SmartPay user accounts to reset your password.
The code goes only to the phone number already on your staff record. If that number is wrong or missing, no code will arrive: ask the Administrator to correct your record or reset your password. Every request is recorded.
