Long time no scolding, is your product manager SB from Binance? Can you copy the anti phishing codes from other companies? How are the 6-8 characters divided into three types: uppercase, lowercase, numbers, and underscores? You either need to increase the length or use pure numbers. Why do you need to use underscores? You also need to include three out of the four types of 6-8 characters. I really want to strip off your product manager's pants and start from behind.
