PIN Generator
Generate cryptographically secure random PIN codes. Perfect for ATM cards, phone locks, app passcodes, and security systems.
Generated values never leave this device.10,000 possible combinations ≈ 13 bits of entropy. Every PIN reads "Weak" on the scale above — that's honest: 4-6 digit PINs are only safe because the systems that use them lock out or rate-limit after a few wrong guesses.
In plain terms: a single gaming PC guessing a million passwords per second would crack this in about under a second. Don’t use it for anything that matters.

PIN Generator Use Cases
ATM & Banking PINs
Debit cards, credit cards, and ATM access. Most banks require 4-digit PINs, though some allow 5-6 digits for enhanced security.
Device PINs
Smartphone screen locks, tablet security, laptop TPM chips, and smart device access codes. 4-6 digits are most common.
SIM Card PUKs
Personal Unblocking Keys for SIM cards are typically 8-digit codes. Essential backup codes for mobile phone security.
Parental Control PINs
TV parental controls, gaming console restrictions, router settings, and streaming service child locks.
App & Service PINs
Banking apps, password managers, secure messaging apps, and financial service passcodes.
Security Systems
Home alarms, building access, safes, keypad locks, and access control systems.
PIN Security Tips
- Avoid obvious PINs: 1234, 0000, 1111, birth years
- Don't use the same PIN for multiple accounts
- Use 6+ digits when possible (100x more combinations than 4 digits)
- Never write your PIN on your card or store it nearby
- Shield the keypad when entering your PIN in public
Most Common PINs to Avoid
These PINs account for over 25% of all 4-digit PINs used. Never use them:
PIN Security FAQ
What makes a PIN secure?
A secure PIN is completely random, not based on personal information (birthdays, addresses), and at least 6 digits when possible. Avoid sequential numbers (1234) or repeated digits (1111).
How many digits should my PIN be?
Use the longest PIN your system allows. 4 digits = 10,000 combinations, 6 digits = 1,000,000 combinations. For critical accounts, always choose 6+ digits when available.
Should I use the same PIN for multiple accounts?
No. Use unique PINs for different accounts and devices. If one PIN is compromised, your other accounts remain secure. Consider using a password manager to track different PINs.
How do I remember multiple random PINs?
Write them down and store securely in a password manager or encrypted note app. For ATM cards, many banks allow you to change your PIN to something more memorable while still secure.
Can someone guess my PIN by watching me type?
Yes, this is called "shoulder surfing." Always shield the keypad when entering your PIN, especially at ATMs and in public places. Be aware of cameras and people nearby.

PIN Length Comparison
| Length | Combinations | Entropy | Time to Guess (3 tries/day) |
|---|---|---|---|
| 4 digits | 10,000 | 13 bits | ~9 years |
| 5 digits | 100,000 | 17 bits | ~91 years |
| 6 digits | 1,000,000 | 20 bits | ~913 years |
| 8 digits | 100,000,000 | 27 bits | ~91,324 years |
Guess times assume the lockout/rate-limiting that banks and devices enforce. Without lockout, any PIN this short is brute-forced instantly.
