How to generate a random PIN

  1. Choose the length: 4 digits, 6 digits, or another size the device allows.
  2. Generate a random PIN. Weak patterns such as 1234, repeats, and keypad walks are discarded.
  3. Copy it. Generation runs in your browser; nothing is sent to a server.

4-digit PIN or 6-digit PIN

4-digit PIN

10,000 combinations. Use it only when the device requires four digits, and generate it randomly instead of using a date or 1234.

6-digit PIN

1,000,000 combinations. Prefer this for phones and apps: a secure PIN starts at six random digits.

Best PIN Practices

✓Do's

  • Use a unique PIN for each device or application.
  • Generate random 6-digit PINs without predictable patterns.
  • Use PINs only for device locks and local authentication.
  • Enable biometric authentication (fingerprint, face ID) when available.
  • Change your PIN if you suspect it's been compromised.

✕Don'ts

  • Never use a PIN as a password for online accounts.
  • Avoid sequential patterns like 123456 or 654321.
  • Don't use birthdates, anniversaries, or personal dates.
  • Never reuse the same PIN across multiple devices.
  • Don't share your PIN with others or write it down visibly.

Check whether a PIN is weak with the PIN strength checker.

For online accounts use the password generator — a PIN is too short for remote login.
