PIN Code Security system

I want to create a PIN codey security system
The criterion is that only numbers should be used and contains 8 characters.

Do you have any idea which component to use??

You can use textbox component and use when textbox.text change block to aim what you are trying

I would personally use s CardView + Label combo to make the UI. I wouldn’t use a textbox for a PIN entry system. Also, for local storage of the correct PIN, I’d hash it with BCrypt or PBKDF2.
