Frequently asked questions
Are these generators safe to use?
Yes. Everything runs in your browser and nothing is sent anywhere. The password and UUID tools use your device's built-in secure randomness, so what they produce never touches a server.
What can I generate here?
Strong passwords with the character sets you choose, random numbers in any range, version 4 UUIDs for databases and testing, and lorem ipsum placeholder text for mockups and layouts.
Do the passwords get stored anywhere?
No. A generated password exists only in your browser until you copy it. Refresh the page and it's gone — nothing is logged, saved, or transmitted.
