Password Generator
Generate strong, random passwords with customizable length and character options. Create secure passwords instantly in your browser.
About Password Generator
Creating strong, unique passwords for every online account is one of the most important steps you can take to protect your digital life. Our free Password Generator builds random passwords right inside your browser, so nothing is ever transmitted over the network or stored on a server.
Why random passwords matter
Attackers rely on predictable patterns - dictionary words, birthdays, pet names, and common substitutions like "p@ssw0rd." A truly random password eliminates these patterns entirely. Even a modest 12-character random password drawn from uppercase, lowercase, digits, and symbols has over 475 sextillion possible combinations, making brute-force attacks computationally infeasible with current hardware.
How to use this tool
Use the slider or input field to choose a password length between 8 and 128 characters. Toggle character categories on or off: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and special symbols (!@#$%^&* and more). Click Generate to create a new password instantly. The color-coded strength meter updates in real time so you can see exactly how secure your settings are before you copy the result.
Best practices
Use a different password for every site. Pair this generator with a reputable password manager so you only need to remember one master password. Regenerate passwords periodically for sensitive accounts, and always enable two-factor authentication when available.
This Password Generator creates credentials you can trust, and it all happens locally in your browser.
Frequently Asked Questions
How does the password generator create secure passwords?
Our password generator uses the Web Crypto API (crypto.getRandomValues) built into your browser to produce cryptographically secure random numbers. These random values are then mapped to your selected character sets to build a password that is truly unpredictable.
What makes a password strong?
A strong password is long (at least 12 characters), contains a mix of uppercase letters, lowercase letters, numbers, and special symbols, and avoids dictionary words or personal information. Our strength indicator evaluates your settings in real time.
Is it safe to generate passwords in a web browser?
Yes. This tool runs entirely in your browser. No passwords are sent to any server, stored in any database, or logged anywhere. Once you close or refresh the page, the generated password exists only if you copied it.
How long should my password be?
Security experts recommend at least 12 to 16 characters for most accounts. For high-value accounts like banking or email, 20 or more characters provide an extra margin of safety against brute-force attacks.
