Secure random PIN generator for 4–12 digit codes.
Create a numeric passcode for a device or service that lets you choose your own PIN. Pick 4, 6, 8 or 12 digits, optionally reject three identical digits in a row, and copy the result. This tool does not issue bank tokens or time-based verification codes.

A PIN has a smaller search space than an alphanumeric password. Always use the longest length the target system accepts.

Fair random selection
Rejection sampling removes modulo bias before values are mapped to characters or words.
PIN security relies on length, randomness, and lockout attempt limits.
A four-digit PIN has only 10,000 possible combinations, while a six-digit PIN has 1,000,000 possibilities. PINs are intended for hardware devices or systems that strictly rate-limit failed guesses.
Practical advice: Use the maximum PIN length supported. Moving from 4 digits to 6 digits increases brute-force complexity by 100x.
Choose 4, 6, 8 or 12 digits
Use a quick-length button or the slider to match the destination's rule. Four digits have 10,000 possible values, six have 1,000,000, eight have 100,000,000 and twelve have 1,000,000,000,000 before optional filtering. Leading zeros are valid digits: copy the whole code and confirm the destination preserves its length.
What the repeated-digit option actually filters
The option rejects runs such as 000 or 777 anywhere in the result. It does not block every date, increasing sequence or keypad pattern. Filtering slightly reduces the possible set; random generation does not mean every human-recognizable pattern is impossible.
Do not use a PIN as a website password
A numeric-only secret is not sufficient for online web services unless backed by multi-factor authentication (MFA) and aggressive server-side rate limiting.
Device-level protections matter
Screen privacy, biometric fallback limits, auto-wipe policies after failed attempts, and secure recovery mechanisms determine whether a device PIN remains secure.
FAQ
Before you use the result.
Is a 6-digit PIN secure?
An unrestricted random 6-digit PIN has 1,000,000 possible values, including leading zeros. Whether it is adequate depends on device protection, attempt limits and recovery rules. Use the longest PIN supported; a short PIN is not a substitute for a full account password.
Why offer an option to avoid repeated digits?
Some users or devices prefer codes without three identical digits in a row. The option rejects those runs and generates another code. It reduces the search space slightly and is not a guarantee against every recognizable pattern.
Can anyone view or retrieve my generated PIN?
No. The PIN is generated via window.crypto.getRandomValues() and only exists in your browser display until the tab is closed or refreshed.
