Password generator

Password generator features

• 01

  Cryptographically random

  Passwords are generated using the browser's built-in crypto API, not a weak Math.random() call. Every character is independently and unpredictably chosen, so the output is as random as a hardware token.

• 02

  Fully configurable

  Dial in the exact length you need (8–128 characters) and toggle uppercase letters, lowercase letters, numbers and symbols independently. The strength indicator updates live so you can see the trade-off immediately.

• 03

  100% private — runs in your browser

  Generation runs entirely in your browser. No passwords, settings or usage data are ever sent to a server, logged or stored. Close the tab and the password is gone — only you have it.

Password generator FAQ

Is it safe to generate passwords online?

Yes, because Handytool's generator runs entirely in your browser using the Web Crypto API. Nothing is transmitted to a server, so there is no point at which a third party could intercept or log your password.

How long should my password be?

Security researchers recommend at least 16 characters for most accounts, and 20+ for high-value targets like email or banking. Longer passwords are exponentially harder to brute-force regardless of the character set used.

Should I include symbols in my password?

Including symbols significantly increases the number of possible combinations (entropy), making passwords harder to crack. However, some sites restrict which symbols are allowed — if a generated password is rejected, try toggling off special characters.

What is the difference between a random password and a memorable one?

A truly random password (e.g. "X7#mQp2!kLr9") has high entropy but is hard to memorise. A memorable passphrase (several random words joined together) can be equally strong while remaining writable. Use a password manager so you only ever need to memorise one master password.

Why use a password generator instead of making one up myself?

Humans are bad at picking random passwords — we gravitate toward patterns, dates and words that are predictable. A generator produces genuinely unpredictable output, removing the human bias that attackers exploit in dictionary and pattern-based attacks.

Is the password generator free?

Yes. Every Handytool is free to use with no sign-up, no usage limits and no ads targeting.
