Random Password Generator
—
🔒 Generated in your browser with secure randomness — never sent or stored anywhere.
About this tool
A random password generator creates a unique, hard-to-crack password using cryptographically secure randomness. You choose the length and character types — upper- and lowercase letters, numbers and symbols — and the password is built right in your browser, never stored or sent anywhere. For the best security, use at least 16 characters and a different password for every account.
How to use it
- Set the password length.
- Choose which character types to include.
- Tap Generate.
- Copy your new password.
How to create a strong password
- Set the length to 16 characters or more.
- Turn on uppercase, lowercase, numbers and symbols.
- Tap Generate until you get one you'll use.
- Copy it and paste it where you're signing up.
- Save it in a password manager and turn on two-factor authentication.
What makes a password strong?
Three things: length, randomness and uniqueness. Length matters most — each extra character multiplies the guesses an attacker needs. Randomness removes patterns a cracker can exploit, and a unique password per account means one leak can't unlock the rest.
How long should it be? Crack time at a glance
| Length | Lowercase only | Upper + lower + numbers + symbols |
|---|---|---|
| 8 characters | Seconds | A few hours |
| 12 characters | A few weeks | Centuries |
| 16 characters | Thousands of years | Effectively uncrackable |
Approximate times for an offline brute-force attack with modern hardware; real figures vary with the attacker's resources. The takeaway holds: every extra character helps far more than swapping one letter for a symbol.
Password vs. passphrase
A passphrase strings several random words together, like correct-horse-battery-staple. It's easy to remember and, thanks to its length, hard to crack. A random password is shorter but denser. Both are strong when they're long and random — pick whichever you'll actually use.
Avoid these weak passwords
These sit at the top of every breached-password list, so they're the first things attackers try:
- 123456
- password
- qwerty
- 111111
- abc123
- Your name, pet's name or birthday
Frequently asked questions
- Is the password generated privately?
- Yes. It's created in your browser with cryptographically secure randomness and is never sent anywhere.
- What makes a strong password?
- Length matters most. Use 16+ characters with a mix of cases, numbers and symbols, and a unique password per account.
- How long should my password be?
- Aim for at least 16 characters; longer is stronger. Length adds far more security than swapping a few letters for symbols.
- How does the random password generator work?
- It uses your browser's cryptographically secure random number generator to pick each character independently. Everything happens on your device — no password is ever sent to or stored on a server.
- Why should I use a password generator?
- People reuse and invent weak, guessable passwords. A generator gives you a long, truly random one in a second, so every account gets unique, strong protection.
- Do I need a unique password for every account?
- Yes. If you reuse one and a single site is breached, attackers try that password everywhere. A unique password per account contains the damage — a password manager makes this easy.
- Is it free and private?
- Completely free, no sign-up. Everything runs in your browser, so nothing you type is uploaded.
