Security tools that Respect your Privacy

Yes. Every tool runs in your browser using the Web Crypto API — the same FIPS-approved cryptographic interface that browsers use for HTTPS connections. For algorithms the Web Crypto API doesn't cover, we use audited open-source libraries.

There are no server logs, no data-in-transit, and no backend breach vector — because no tool data is ever sent to a server. You can verify this yourself by opening your browser's network tab while using any tool.

Passwords are generated using cryptographically secure pseudo-random number generators (CSPRNG) from your browser's Web Crypto API — the same randomness source that powers TLS encryption keys. BetterPass never uses weak methods like Math.random().

Each character is chosen from your specified character set using unbiased random bytes. You can customize length, character types, and even exclude specific characters. The resulting password's entropy is displayed on screen in bits, so you always know exactly how strong it is.

The Web Crypto API is a built-in browser standard (W3C Recommendation) that provides low-level cryptographic primitives to web applications — including secure random number generation (crypto.getRandomValues), hash functions (SHA-256, SHA-512), HMAC, PBKDF2, and digital signature verification.

Unlike JavaScript-only crypto libraries, the Web Crypto API is implemented in native code by the browser vendor. This makes it both faster and more trustworthy than any JavaScript library could be. BetterPass relies on it as the foundation for most of its tools.
