PIN generator
Choose your options, then generate a new secret.
Entropy / upper bound (bits)—
Choose 4–12 random digits. Leading zeros are preserved. A short PIN needs attempt limits on the service where it is used.
A heuristic is not a security guarantee. The entropy figure is an upper bound, not measured resistance to guessing. No breach database is queried. Use unique passwords and enable multifactor authentication.
Privacy
Passwords and PINs are generated or analyzed in browser memory. This application does not send them to the server, save them, put them in URLs or log them. No advertising, analytics, external scripts, cookies or browser storage are used. Copying explicitly writes to your system clipboard; other software or clipboard history may retain it. Navigation clears the interface. The hosting server can receive ordinary technical request data, such as IP address and requested path; its log policy must be verified by the operator before deployment.

Every selected group is included. Ambiguous characters can be excluded. The displayed entropy is an upper bound because group requirements reduce the space of possible outputs.Choose 3–12 independently selected words from a bundled English list. The interface language does not translate the generated words. Capitalization and separators add no randomness. Two optional digits add log₂(100) bits.Choose 4–12 random digits. Leading zeros are preserved. A short PIN needs attempt limits on the service where it is used.A little length goes a long wayLonger randomly chosen secrets have more possibilities. A passphrase combines random words for easier reading; a password uses random characters. We use crypto.getRandomValues and unbiased selection rather than Math.random.
