Frequently Asked Questions
Are passwords generated here truly random?
Yes. We use the browser's crypto.getRandomValues() API which is a cryptographically-secure source of randomness → the same standard used by banks and SSL libraries. There's no predictable pattern.
Is the generated password sent to your servers?
No. Generation happens entirely in your browser. Nothing is logged, transmitted, or stored anywhere by ToolPix. You can verify by going offline → the tool still works.
How long should my password be?
16+ characters with mixed case, numbers, and symbols is the modern minimum. 20+ characters is bank-grade. Each extra character roughly doubles the time required to crack it.
What does "entropy" mean?
Entropy measures unpredictability in bits. 60 bits = strong; 80+ bits = very strong; 100+ bits = takes centuries even on supercomputers. The slider's "Time to Crack" assumes 10 billion guesses per second.
Should I use a password manager?
Always. Even the strongest password is useless if you reuse it. Use 1Password, Bitwarden, or your browser's built-in manager to store unique, randomly-generated passwords for every account.
Why are some sites refusing my password?
Some legacy sites have arbitrary limits like "max 16 characters" or "no symbols". If your password is rejected, lower the length or uncheck symbols and regenerate.
About this tool → Strong Password Generator
Our password generator creates cryptographically-secure random passwords using the browser's built-in crypto.getRandomValues() API → the same source of randomness used by SSL libraries and banking apps. Length, character classes, and exclusion of look-alike characters are all configurable. The resulting password never leaves your device: no logging, no analytics, no transmission.
What makes a password "strong"?
Strength is measured in bits of entropy — a logarithmic measure of how many guesses an attacker would need on average to break the password. Each bit roughly doubles the cost. Modern guidance:
Under 50 bits — weak. A botnet can brute-force this in hours.
60—80 bits — strong. Resistant to most online and many offline attacks.
80—100 bits — very strong. Even nation-state attackers would need years.
100+ bits — overkill for almost everything. Required for cryptographic keys.
A truly random 16-character password drawn from upper, lower, digits and symbols (— 95 possible characters per slot) gives roughly 105 bits of entropy → well past the "very strong" threshold.
Why length beats complexity
The most important factor is length. A 20-character password using only lowercase letters has more entropy than a 12-character password packed with symbols. That is why password managers default to 16+ characters with mixed classes → it gives you both length and character diversity. Avoid the common pattern of "Capital + word + number + symbol" (like Password123!); attackers know this template and crack it in seconds.
Best practices in 2026
Use a password manager. 1Password, Bitwarden, KeePass, or your browser's built-in vault. The strongest password is useless if you reuse it across sites.
Generate a unique password per site. Re-using passwords means one site's data breach instantly compromises your other accounts (this is called "credential stuffing").
Aim for 16+ characters. Below 14 starts to look attackable as GPU farms get faster every year.
Enable 2FA wherever possible. Even a perfect password fails if someone phishes you. Use a TOTP app (Authy, Google Authenticator) or hardware key (YubiKey).
Never store passwords in plain-text files or send them via email or chat. If you must share, use a one-time secret service like the encrypted-text features in 1Password or Bitwarden.
Check for breaches. Visit haveibeenpwned.com regularly to see if any of your accounts were exposed.
Are passwords generated here ever logged?
No. There is no fetch, no analytics on the password value, no server-side handling at all. The password lives only in the JavaScript variable on your page, plus the clipboard if you copy it. Closing the tab destroys the value. You can verify by opening the browser's Network tab → generating a new password makes zero network requests.
