PIN Generator
Generate random numeric PIN codes (digits only). Choose length and how many PINs to generate. Copy results with one click.
Common lengths: 4 or 6. Short PINs have limited combinations.
Uniqueness is not guaranteed. With 4 digits there are only 10,000 possible PINs (0000–9999).
Privacy: Generated locally in your browser. No PINs are stored or sent to a server.
How it works
- Choose a PIN length and count.
- Optionally disallow leading zeros and/or add a numeric prefix/suffix.
- The tool draws random digits and formats each PIN.
Examples
- 4-digit PIN, count 10 → quick set of test PINs
- 6-digit PIN, no leading zero → common OTP-style format
- Prefix 99 + length 4 → generates PINs like 99xxxx (overall length increases)
FAQ
- Is this PIN generator secure?
It uses your browser’s cryptographically secure random generator (crypto.getRandomValues) when available. If not available, it falls back to Math.random, which is not suitable for security-critical use.
- Can I generate 4-digit or 6-digit PINs?
Yes. Choose the length (typically 4 or 6). You can generate multiple PINs at once.
- Are duplicate PINs possible?
Yes. Random generation can produce duplicates. You can enable best-effort uniqueness, but it is not guaranteed—especially with short PIN lengths and large counts.
- Does this store or send my PINs anywhere?
No. Everything runs locally in your browser. Nothing is uploaded or stored by this tool.
- Is a PIN the same as a password?
No. PINs are shorter and generally weaker. For accounts, prefer long unique passwords or a password manager.
