Generators calculators
Tools that produce something rather than compute it: strong random passwords, and more to come. Everything is generated in your browser with the system’s cryptographic random source; nothing is sent to a server, and nothing is logged.
Most used

Questions about these calculators
Is it safe to generate a password on a website?
Here, yes: the password is created on your device with the browser’s cryptographic generator and never transmitted. You can disconnect from the internet and it still works.
Why not use my password manager’s generator?
You should, for everything it stores. This page is for the cases where you need one quickly, and for understanding what makes a password strong.
What else is coming?
Random numbers, usernames, and other generators are on the list.
