Online generators

Quickly create random data, passwords and numbers

What are CalcGuru online generators

The Generators section creates random and cryptographically strong data in your browser: secure passwords and random number sets. Generation happens on your device β€” passwords and numbers are not sent to or stored on the server.

Use the password generator for new accounts and the random number generator for giveaways, lotteries, games, and any fair random pick in a range.
