I have a passcode with 4 numbers, how many combinations are there? The password can't have any of the same numbers and you can enter the code in whatever order. So, if the code is 1234, can you also enter: 4321?
Okay, I understand. How secure is a 4-digit passcode with unique numbers?
A 4-digit passcode with unique numbers can be secure, but it depends on how difficult it is for someone to guess or figure out the passcode. It's recommended to use longer passcodes or passwords with a combination of letters, numbers, and symbols for stronger security.
