Free Password Generator: Create Strong, Random Passwords

Weak and reused passwords are behind most account breaches. This free tool creates strong, random passwords and memorable passphrases in seconds, directly in your browser. Nothing you generate is sent to a server, logged, or saved anywhere.

Why You Need a Strong, Unique Password

Attackers rarely guess passwords one at a time. They run automated tools that test billions of combinations per second, plus lists of passwords leaked from earlier data breaches. A short or common password can be cracked in moments, and so can a strong one if you’ve already used it on a site that was breached.

Two things make a password hard to crack: length and randomness. Each extra character sharply increases the number of possible combinations. Randomness matters because it stops attackers from taking shortcuts based on dictionary words, names, or keyboard patterns.

How to Use the Password Generator

1. Choose a mode. Switch between a random Password or a Passphrase built from real words that’s easier to type and remember.
2. Set the length. Drag the slider to your preferred length. For important accounts, aim for at least 16 characters.
3. Pick character types. Turn on uppercase, lowercase, numbers, and symbols.
4. Generate and copy. Regenerate until you’re happy, then copy the result and paste it into your password manager.

Passwords vs. Passphrases

A random password like QX,toA#tg9sVh fits a lot of strength into a short string, which works well when a password manager remembers it for you. A passphrase like Curl-Swoop-Snap-Tweet joins several random words together. It’s just as hard to crack once it’s long enough, but much easier to type by hand, which makes it a good fit for device logins, Wi-Fi, or a master password. The passphrase mode picks words at random from a large word list, so the result stays unpredictable.

What Makes a Password Strong?

• Length matters most. Aim for 16 characters or more. A long passphrase can be stronger than a short string of symbols.
• Keep it random. Avoid names, dates, and keyboard runs like qwerty. This tool uses your browser’s cryptographically secure random generator.
• Make every password unique. Use a different one for each account so a single breach can’t unlock the rest.
• Don’t reuse or share. Keep your passwords in a reputable password manager rather than a notebook or spreadsheet.

Is This Password Generator Safe?

Yes. The tool runs entirely in your browser using the standard Web Crypto API. Passwords are created on your device and are never sent across the internet, saved to a database, or seen by anyone else. You can test this by turning off your internet connection: the generator still works. For extra protection, paste new passwords straight into a password manager and turn on two-factor authentication (2FA) wherever a site offers it.
