What randomness source does the generator use?

The generator uses the browser crypto API, crypto.getRandomValues, instead of Math.random for password, passphrase, and PIN generation.

Does the security model protect against compromised devices?

No. Local generation does not protect against malware, malicious extensions, clipboard monitoring, or a device that is already under someone else's control.

Cryptographically Secure Password Generator

Secure Password Generator is a static browser application. Its main security goal is simple: create passwords, passphrases, and PINs locally so the generated secret does not need to leave your device.

Open the generator

Local generation

The generator logic runs in JavaScript in your browser. Generated values are displayed on the page for you to copy, but they are not submitted to a backend password-generation service.

The important distinction is where the secret is created. This tool creates the password in the browser, so the generated value is not required as input to any server-side generation endpoint.

Randomness

The app uses the browser cryptography API, crypto.getRandomValues, to draw random values for generated secrets. This is more appropriate for password generation than general-purpose functions such as Math.random.

About crypto password generator searches

Some people search for a crypto password generator when they mean a cryptographically secure random password generator. This tool creates passwords with browser cryptography, but it is not designed to create cryptocurrency wallet seed phrases, private keys, or recovery phrases.

What stays local

The generated password, passphrase, or PIN displayed in the output field.
The selected length, character options, and passphrase or PIN settings used by the page.
The entropy and search-space calculations shown beside the generated value.

Tracking and storage

No account is required.
No analytics or advertising scripts are included in this static version.
Generated passwords are not stored by the application.
Important generated passwords should be saved in your own trusted password manager.

Limits of a browser tool

A browser password generator cannot protect against malware, compromised browser extensions, clipboard monitoring, or a device that is already under someone else's control. Use a clean device and a trusted password manager for high-value accounts.

Recommended safe workflow

Generate passwords on a trusted device and browser profile.
Use a new random password for every account, especially email and recovery accounts.
Save important passwords immediately in a trusted password manager.
Turn on multi-factor authentication for accounts that support it.
