CyberCodePassword Generator
Free online password generator. Create strong, cryptographically secure random passwords with custom length, uppercase, lowercase, numbers and symbols. All generated in your browser — never uploaded.
What makes a generated password strong?
Password strength is measured in entropy — the number of guesses an attacker needs. Length beats complexity: a random 16-character password with letters, digits and symbols has about 105 bits of entropy, which is beyond any realistic cracking capability, while an 8-character one (~52 bits) can fall to modern GPU rigs.
This generator uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure randomness used by password managers — not the predictable Math.random(). Passwords are generated on your device and never transmitted.
How to use
- 01Set the desired password length using the slider (8–64 characters).
- 02Toggle which character types to include: uppercase, lowercase, numbers and symbols.
- 03Click Generate Password to create a cryptographically secure random password.
- 04Check the strength indicator, then copy the password to your clipboard.
Frequently asked questions
- How are the passwords generated?
- Passwords are generated using the Web Cryptography API (crypto.getRandomValues), which provides cryptographically secure random values. This is the same standard used by password managers.
- Are generated passwords stored or sent anywhere?
- No. Password generation happens entirely in your browser. The password is never sent to any server and is not stored anywhere.
- What is a good password length?
- Security experts recommend at least 16 characters for important accounts. Longer passwords with a mix of all character types are significantly harder to crack.
