Password Generator
Generate strong, unique passwords instantly. 100% client-side — never sent to any server.
🔒 All passwords are generated locally in your browser using crypto.getRandomValues(). Nothing is transmitted to any server.
About the Password Generator
This password generator creates strong random passwords with adjustable length and character sets. Generation uses your browser's cryptographic random source, and nothing is ever transmitted, logged or stored — the only acceptable arrangement for a tool that produces secrets.
A password generator removes the weakest link in password security, which is human invention. People reuse, substitute predictable characters and build passwords around words — all patterns that cracking tools exploit first.
Length matters far more than complexity. Each additional character multiplies the search space, so a long password drawn from a smaller set beats a short one stuffed with symbols. Sixteen characters is a reasonable floor for anything important, and twenty or more for a password manager's master password.
Because generation happens in your browser using the cryptographic random source, no password is ever transmitted or recorded — which is the only acceptable arrangement for a tool like this. Store the result in a password manager rather than reusing it anywhere.
How to use the Password Generator
- Set the length. Choose at least 16 characters for anything important.
- Pick the character sets. Include uppercase, lowercase, digits and symbols as the site allows.
- Generate. A new password is produced from the browser's secure random source.
- Save it to a manager. Copy the password straight into a password manager rather than reusing it.

Frequently asked questions
How secure are the passwords generated?
Our password generator uses the Web Crypto API's cryptographically secure random number generator (CSPRNG) with window.crypto.getRandomValues(). This provides industry-standard randomness suitable for high-security applications, meeting NIST and other security standards.
What password options can I customize?
Customize password length (1-128 characters), include/exclude uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous characters (I, l, 1, O, 0) to improve readability and prevent transcription errors.
What makes a password strong?
Strong passwords use long length (16+ characters), mixed character types (uppercase, lowercase, numbers, symbols), avoid dictionary words or personal information, and are unique for each account. Our strength analyzer evaluates these factors to provide real-time feedback.
Are generated passwords stored or tracked?
No! Passwords are generated entirely in your browser using client-side JavaScript. Nothing is sent to our servers, and no passwords are stored, logged, or tracked. Each generation is completely independent and private.
What password length should I use?
For most accounts, 12-16 characters provide excellent security. For high-value accounts (banking, email), use 20+ characters. Modern computers can brute-force shorter passwords quickly, but longer passwords exponentially increase difficulty. Our tool supports up to 128 characters.
Can I generate multiple passwords at once?
Yes! Generate multiple passwords simultaneously for different accounts or to have backup options. Each password is independently generated with the same cryptographic security, ensuring no correlation between generated passwords.
