A PIN code is typically a short sequence of numbers, often 4 or 6 digits, used for security purposes. It's used to authenticate users for various things, such as:
* ATM transactions: To access your bank account at an ATM.
* Debit/Credit cards: For making purchases or accessing your account online.
* Mobile phones: To unlock your device and access protected apps.
* Online accounts: To log in to websites and services.
PIN codes are NOT:
* Passwords: Passwords can be longer and include letters, numbers, and symbols.
* PAS codes: There's no common abbreviation "PAS" used for security codes.
Important Note: Keep your PIN code secret and don't share it with anyone. If you suspect your PIN code has been compromised, change it immediately.
