Weak passwords cause 80% of data breaches. "123456", "password", your pet's name — these take hackers less than a second to crack. If you're using the same simple password across multiple accounts, you're putting all of them at risk.
Our free password generator creates strong, random passwords instantly. No signup, works in your browser, your passwords are never sent anywhere.
What Makes a Password Strong?
A strong password has these characteristics:
- 12+ characters long — Longer is stronger
- Mix of character types — Uppercase, lowercase, numbers, symbols
- No dictionary words — "correct horse battery staple" style is better than single words
- No personal info — No birthdays, names, or pet names
- Unique per account — Never reuse passwords
Password Strength Comparison
| Password | Length | Time to Crack |
|---|---|---|
| 123456 | 6 chars | Less than 1 second |
| password1 | 9 chars | ~3 hours |
| MyDogMax | 8 chars | ~2 hours |
| Tr0ub4dour&3 | 12 chars | ~3 days |
| k9#Lm2$xP8@q | 12 chars | ~3 thousand years |
| a7Km!2xP8@qR3nW5 | 16 chars | ~38 quintillion years |
The difference between a weak and strong password is astronomical. Use our password generator to always create strong ones.

Password Best Practices
1. Use a Password Manager
Don't try to memorize 50 different passwords. Use a password manager like Bitwarden (free), 1Password, or LastPass to store all your passwords securely. You only need to remember one master password.
2. Enable Two-Factor Authentication (2FA)
Even if someone gets your password, they can't access your account without the second factor. Enable 2FA on every account that supports it — especially email, banking, and social media.
3. Never Reuse Passwords
If one service gets breached and you used the same password elsewhere, all those accounts are compromised. Always use unique passwords.
4. Change Passwords After Breaches
If a service you use gets hacked, change your password immediately. Check Have I Been Pwned to see if your email has been in a breach.
5. Don't Share Passwords
Not with friends, not over email, not over text. If you must share access, use a password manager's sharing feature.
Common Password Mistakes to Avoid
- Using "password" or "123456" — These are the first things hackers try
- Using personal information — Your name, birthday, and pet's name are easy to find on social media
- Substituting numbers for letters — "p@ssw0rd" is not much harder to crack than "password"
- Using keyboard patterns — "qwerty" or "asdfgh" are in every cracking dictionary
- Saving passwords in browser — Browsers store passwords in plain text unless you use a master password
- Using the same password everywhere — One breach compromises everything
How Hackers Crack Passwords
Understanding the threat helps you stay safe:
Brute Force Attack
Trying every possible combination. A 12-character password with symbols takes thousands of years to brute force. A 6-character password takes seconds.
Dictionary Attack
Trying common words and variations. "Sunshine1", "LetMeIn!", and "Welcome2024" are all in cracking dictionaries.
Credential Stuffing
Using leaked username/password combos from data breaches on other services. This is why you should never reuse passwords.
Phishing
Tricking you into entering your password on a fake website. Always check the URL before entering credentials.
Password Security FAQ
How often should I change my password?
Only when there's a reason — like a data breach or suspected compromise. Regular forced changes lead to weaker passwords (Password1, Password2, Password3...).
Should I write down my passwords?
Writing passwords on paper is actually safer than reusing them. Keep the paper in a secure location. Better yet, use a password manager.
Are password managers safe?
Yes. Password managers encrypt your vault with a master password. Even if the company gets hacked, your passwords remain encrypted and unreadable.
What's a passphrase?
A passphrase is a password made of multiple random words: "purple-tiger-slide-kitchen-forty". Passphrases are long, strong, and easier to remember than random characters.
Is it safe to use an online password generator?
Our generator runs entirely in your browser using JavaScript. The passwords are never sent to any server. You can verify this by disconnecting your internet — the generator still works.
