Reused and predictable passwords are behind a large share of account breaches, and the fix is simple: use a long, random, unique password for every account. The Password Generator creates exactly that — a strong, unpredictable password built from the character sets you choose, generated the instant you open the page. Set the length, decide whether to include uppercase letters, numbers, and symbols, and copy the result straight into your password manager.
Security starts with how the password is made. This tool generates passwords locally in your browser using the cryptographically secure random number generator built into modern browsers. The password is never sent over the network, never logged, and never stored anywhere. Refresh the page and it is gone for good.

How to use the Password Generator
Choose your desired password length using the slider or input. Toggle which character types to include — lowercase, uppercase, numbers, and symbols. A new password is generated immediately, and you can regenerate as many times as you like until you get one you want. Click to copy it, then paste it directly into the signup or password-change form where you need it.
Features
You control password length and can mix lowercase and uppercase letters, digits, and special symbols. Each generation draws from a cryptographically secure random source rather than a predictable pseudo-random one, and the tool produces a new password instantly on demand. Everything happens client-side, so no password ever touches a server.
Common use cases
Use it whenever you create a new account, rotate an old or possibly compromised password, or set up credentials for a database, server, or API. IT administrators generate passwords for new users, developers create secure secrets for environment variables, and everyday users strengthen weak passwords on important accounts like email and banking.
Security and how it works
The generator uses the browser's Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness suitable for security purposes — unlike Math.random(), which is predictable and should never be used for passwords. Because generation happens entirely in your browser, the password is created and displayed locally and is never transmitted or saved. For maximum safety, generate the password, paste it into a reputable password manager, and never reuse it across sites.
Frequently asked questions
Are the generated passwords stored anywhere?
No. Passwords are generated locally in your browser and are never stored, logged, or sent to any server.
How random are the passwords?
They use the browser's cryptographically secure random generator (Web Crypto API), which is appropriate for security-sensitive use.
How long should my password be?
For most accounts, 16 characters or more with mixed character types is a strong choice. Longer is always safer.
Can I generate passwords without an internet connection?
Yes. Once the page has loaded, generation works offline because it runs entirely in your browser.
Is it safe to generate passwords in a browser?
Yes, when the tool runs locally and uses a secure random source, as this one does. Always paste the result into a trusted password manager.
