About Password Generator

Most online password generators send your request to a server, where the generated value sits in logs you'll never see. Berlvis Password Generator uses the Web Crypto API (crypto.getRandomValues) right inside your browser, so the password literally exists only on your device. Pick length, character classes and copy with one click.

Frequently asked questions

+Is Password Generator really free?

Yes. Every Berlvis tool is free, with no signup, no email and no daily quota.

+Do you upload my files or data?

Never. Your file stays in your browser, nothing is uploaded, nothing is logged, nothing leaves your device.

+Will it work on my phone?

Yes, anywhere there's a modern browser (Chrome, Safari, Firefox, Edge, Brave, Arc).

+How accurate is the calculation?

We use the same formulas you'd find in official guidance and primary tax/regulatory sources. Numbers are calculated client-side so what you see is what's used, nothing hidden.
