PIN Code Generator
Generate random 4-12 digit PIN codes for bank cards, door locks and alarms using cryptographic randomness
PIN Code Generator
- 4 digits: ATM cards, phone unlock
- 6 digits: 2FA codes, smart locks
- 8+ digits: High-security systems
Warning: Never use birthdays, 1234, or 0000 as your PIN!
How to Use PIN Code
- 1 Select PIN length (4-12 digits)
- 2 Click "Generate" for a new PIN
- 3 Avoid obvious patterns like 1234, 0000, or birth years
- 4 Write it down securely or memorize it
What You Get
Random digits 0-9 generated using the Web Crypto API. Each digit adds ~3.3 bits of entropy.
Input: 4 digits
Output: 7392
Input: 6 digits

How do I generate a random PIN code?
Select PIN length (4-12 digits), click Generate. We use cryptographic randomness, not Math.random().
Is a 4-digit PIN secure?
For physical devices with attempt limits (ATM cards, phones), yes. For online accounts, use 6+ digits or a full password.
Should I use my birthday as a PIN?
Never. Birthdays, anniversaries, and years are the first things attackers try. Use truly random digits.
What about repeating digits like 1111?
Random generation may produce repeats. Mathematically, 1111 is just as secure as 7392 since attackers try all combinations.
How long should a PIN be?
4 digits for bank cards (with attempt limits). 6+ for digital locks or apps. 8+ for high security needs.
How many combinations does a 4-digit PIN have?
10,000 combinations (0000-9999). A 6-digit PIN has 1 million. Each digit adds 10× more combinations.
Is my PIN stored anywhere?
No. Generated 100% locally in your browser. Nothing is ever sent to any server. Write it down securely or memorize it.
Can I generate multiple PINs at once?
Click Generate multiple times to get different options. Each generation is completely random and independent.
