Free Random Password & Key Generator
Create strong passwords, API keys, UUIDs and more — instantly on your device. Nothing leaves your browser.
- Go long Use at least 16 characters. Every extra character makes brute-force attacks exponentially harder.
- Mix character types Combine upper and lower case, numbers and symbols. Predictable patterns are the first thing attackers try.
- Never reuse One leak can compromise every account that shares the same password. Use a unique secret for each service.
Is this generator safe to use?
Generation uses your browser's cryptographic random number generator. Passwords and keys are created locally. They are not sent to us.
How should I store generated secrets?
Use a password manager like PassRepo. Avoid plain text files, chat messages or browser notes — they are easy to leak.
Can I generate API keys here?
Yes. Switch to the API Key tab to create hex or base64url tokens with an optional prefix — ideal for development and testing.
Does it work offline?
Generation does not need the internet. The page loads once. The breach check looks up an online list; if that fails, generation still works.
