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 and generate one code or 10 or 25 unique codes for test data or manual device setup. Copy the result or download TXT. This tool does not issue bank tokens or time-based verification codes.

Secure PIN generator● Web Crypto ready
The pool-based estimate is per PIN, before repeated-digit filtering. Use the longest length accepted. TXT exports contain plaintext codes; protect them and delete unneeded copies.

Results are never written to cookies, local storage, session storage, or a database.
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 a random PIN length.
4-digit PIN generator
Use four digits only when the destination requires that length. With so few possible codes, failed-attempt limits and device protections are essential.
10,000 possible strings before filtering, including codes that start with zero.
6-digit PIN generator
Six digits offer 100 times as many possible codes as four digits before filtering. Choose this length when the device or service accepts a six-digit PIN.
1,000,000 possible strings before filtering, including codes that start with zero.
8-digit PIN generator
Eight digits provide more guessing resistance when supported, but do not make a numeric code equivalent to a long account password or an automatically expiring OTP.
100,000,000 possible strings before filtering, including codes that start with zero.
Leading zeros count toward the length. 0042 is a four-digit format example, not a recommended code. Copy the entire result and confirm that the destination keeps every digit.
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.
Generate a small batch without losing leading zeros
Choose 10 or 25 PINs for test fixtures or manual device setup. Codes are unique within the displayed batch, not across previous batches. Copy and TXT download use one code per line and keep leading zeros. If you later import the file into a spreadsheet, set the column type to Text; converting a code to a number can remove its leading zeros.
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 a random PIN start with zero?
Yes. Zero is a valid first digit here, and the result is kept as text. For example, 0042 is a four-digit code, not the number 42. This is a public format example, not a PIN to use. Check that your destination accepts and preserves leading zeros.
Can I generate multiple PINs at once?
Yes. Choose 10 or 25 PINs, select a length, then copy the newline-separated list or download TXT. Each displayed batch contains unique codes. No comparison is made with earlier batches, and no accounts or time-based one-time codes are created.
Can the website retrieve my generated PIN?
Generation uses window.crypto.getRandomValues() in your browser, without a generation request or saved history. Anyone who can see your screen, clipboard or downloaded TXT file may still read the PINs. Protect those copies; the site cannot recover a previous result.
