Hello! Do you know what are the PIN numbers that can hard to guess? My sister can know these PIN numbers (ex. 2*****, 5***, ****) even when my Galaxy J6 has charging and I taking a nap when I'm tired & Didn't use for a while. I hope my sister doesn't know the PIN at all. I use fingerprint and face recognition than PIN. I want a PIN number contains at least 4 -8 digits. Thanks for your advance😊
