Password Generator
Create a strong, truly random password in your browser. Cryptographically secure, fully private, and free — with controls for length and character types.
How this password generator works
This generator builds passwords using your browser’s cryptographically secure random number generator (crypto.getRandomValues), the same primitive recommended for security-sensitive randomness. Nothing is transmitted — the password is created on your device and never leaves it. Choose a length and the character classes you want, and a fresh password appears instantly.
The entropy figure shown beneath each password estimates its strength in bits. Entropy measures how many guesses an attacker would need on average; every extra bit doubles that number. As a rule of thumb, aim for at least 75–80 bits for important accounts, which a 14–16 character mixed password comfortably exceeds.
How to use a generated password safely
Generate, then copy once
Click Generate until you get a password you are happy with, then press Copy. Paste it straight into the new-password field of the account you are securing.
Store it in a password manager
You should never have to memorise these. Save it in a password manager so it auto-fills next time. That way every account can have a unique, maximum-strength password.
Turn on two-factor authentication
Even a perfect password is stronger with a second factor. See our guide to two-factor authentication for the most important accounts.
Why random beats clever. Patterns you invent (Pa$$w0rd!, name+year) are exactly what cracking tools try first. True randomness has no pattern to exploit — which is why generated passwords are so much harder to crack. Learn more in how to create strong passwords.
Frequently asked questions
Are these passwords really random and safe?
Yes. They are generated locally in your browser using the Web Crypto API (crypto.getRandomValues), a cryptographically secure random source. Nothing you generate is sent to Tudug or stored anywhere — close the tab and it is gone.
How long should my password be?
For important accounts, 14–16 characters with mixed character types is a strong, practical choice. Longer is better; a password manager means length costs you nothing because you never type it manually.
Should I use symbols?
Including symbols increases the character pool and therefore strength, but length matters more. A long password without symbols can be stronger than a short one with them. Use both length and symbols where the site allows.
Is it safe to copy a password to the clipboard?
It is fine for a moment, but some apps can read the clipboard. Paste it into your password manager promptly, and avoid leaving sensitive text on the clipboard. Many password managers clear it automatically.
Do I need a different password for every account?
Yes. Password reuse is the single biggest avoidable risk — one breached site exposes every account sharing that password. A unique generated password per site, stored in a manager, closes that gap.
