Password Generator
Strong, random passwords
Generated locally with the Web Crypto API — nothing is ever sent or stored.
What Is the Password Generator?
The Password Generator creates strong, random passwords with full control over length and character sets — uppercase, lowercase, numbers, and symbols — alongside a live strength meter. Passwords are generated locally using a cryptographically secure random source, so they are never transmitted, making this a safe way to produce credentials you can trust.
Key Features
What Makes a Password Strong
Password strength comes from length and randomness, not clever substitutions. A long password drawn from a large character set has so many possible combinations that brute-forcing it is infeasible. Predictable patterns, dictionary words, and personal information weaken passwords no matter how complex they look, which is why random generation is best.
Why Generate Passwords Locally
A password is only secret if no one else ever sees it. This generator uses your browser’s cryptographically secure random number generator and never sends the result anywhere, so the password exists only on your device until you save it. Pair it with a password manager and a unique password per site for real security.
Common Use Cases
- Creating a unique password for a new account
- Generating credentials for a password manager
- Producing secure random keys or secrets
- Replacing weak or reused passwords
Frequently Asked Questions
Are these passwords truly random?
Yes. The generator uses the Web Crypto API’s cryptographically secure random number generator, which is suitable for security purposes — far stronger than ordinary pseudo-random functions.
How long should my password be?
Aim for at least 16 characters for important accounts. Length is the biggest factor in strength, so a longer password from a mix of character sets is dramatically harder to crack.
Is it safe to generate passwords online?
With this tool, yes. Passwords are generated entirely in your browser and are never sent to or stored on a server, so they remain private to your device.
Should I exclude ambiguous characters?
If you may type the password by hand, excluding lookalikes such as l, 1, O, and 0 reduces errors. For passwords stored in a manager, leaving them in adds a little extra entropy.
Do I need a different password for every site?
Yes. Reusing passwords means one breach compromises many accounts. Generate a unique password per site and store them in a password manager so you only need to remember one master password.
