Password Generator
Create strong random passwords. Nothing's saved, nothing's logged. Just copy and paste into your password manager.
Why Use Random Passwords?
Your brain is terrible at making random passwords. We all default to patterns - "Summer2024!" or "MyDog123" or using the same password everywhere with minor tweaks. Hackers know this. Their password-cracking tools check common patterns first.
A truly random password like aK9$mP2@rT5!qL7
doesn't have any pattern. It's just noise. Which means the only way to crack it is brute force -
trying every possible combination. With a long enough password, that's mathematically impossible
within your lifetime.
This tool generates completely random passwords using your browser's cryptographic random number generator. We don't see it, don't log it, don't store it. Generate, copy, paste into your password manager, done.
💡 Expert Tips
Length Beats Complexity
A 20-character password with just lowercase letters is harder to crack than a 10-character password with every symbol ever invented. Length adds exponentially more possibilities. So when a site says "minimum 8 characters" - make it 16 or more.
Use a Password Manager, Seriously
Don't write passwords in a notebook. Don't save them in a text file on your desktop. Get a proper password manager (Bitwarden is free and open-source). Generate random passwords for everything, let the manager remember them. You only need to memorize one master password.
Turn On 2FA Wherever Possible
Even a perfect password can be stolen in a data breach. Two-factor authentication (2FA) means they also need your phone or security key to get in. Use an authenticator app (not SMS if you can avoid it). It's the single best security upgrade you can make.

⚠️ Common Mistakes
Reusing Passwords Across Sites
"I use the same strong password for everything" - no. When LinkedIn gets breached (happened in 2012, 117 million passwords leaked), hackers try those passwords on Gmail, Facebook, banking sites, everything. One breach compromises all your accounts.
Why it happens: People don't want to remember 50 different passwords.
Fix: Password manager. Generate unique random passwords for every site. Let
the software remember them.
Making "Memorable" Passwords
"MyDog'sName2024!" feels random to you, but it fits a pattern hackers specifically check for: [Word][Possessive][Number][Punctuation]. Password crackers have dictionaries of common words, they try numbers at the end, they try common substitutions (@ for a, 3 for E).
Real consequence: Your "clever" password gets cracked in minutes.
Fix: Stop trying to be clever. Random is better. Let this tool generate
nonsense you'll never remember.
Trusting "Security Questions"
"What's your mother's maiden name?" or "What city were you born in?" - this info is often publicly available or easily guessed. Treat security questions like passwords: give random nonsense answers and store them in your password manager.
How to avoid: Mother's maiden name? Enter a random string like "7kP#vQ9m". Store it in your password manager with a note.
How to Use This Generator
- Set Password Length: Start with 16 characters. Go longer (20-25) for important accounts like email or banking.
- Pick Your Options: Keep everything checked unless the site has weird restrictions (some don't allow symbols).
- Click Generate: You'll get a random password. Don't like it? Click again for a new one.
- Copy to Password Manager: Click "Copy to Clipboard" then paste it into your password manager. Don't try to memorize it.
Recommended Length by Account Type:
• Social media, shopping: 12-16 characters
• Email, banking, work accounts: 20-25 characters
• Password manager master password: 25-30 characters (or use a passphrase)
• Disposable/temporary accounts: 10-12 characters (who cares)

Frequently Asked Questions
How long should my password be?
Minimum 12 characters for most accounts. 16+ for important stuff (email, banking). Longer is always better - a 20-character password is exponentially harder to crack than a 12-character one. Some security experts recommend 20-25 characters if the site allows it.
Should I include symbols in my password?
Yes, if the site allows it. Symbols (!@#$%^&*) add complexity and make brute-force attacks way harder. But honestly, length matters more than complexity. A 20-character password with just letters and numbers is stronger than a 10-character password with every symbol you can type.
Is this password generator safe to use?
Yes. The passwords are generated entirely in your browser using JavaScript's random number generator. We don't send anything to our servers, don't log anything, don't store anything. Generate, copy, close the tab - we never saw it.
How do I remember these random passwords?
You don't. Use a password manager (1Password, Bitwarden, LastPass, etc.). They store all your passwords encrypted behind one master password. Generate a random password here, paste it into the password manager, done. Don't try to memorize 'aK9$mP2@rT5' - that's what computers are for.
Can I use the same password for multiple sites?
No. Never. When one site gets hacked (and they all get hacked eventually), attackers try your leaked password on every other site. Use unique passwords everywhere. That's why password managers exist - so you don't have to remember 50 different random strings.
Dr. Alex makes sure the password generation uses cryptographically secure randomness and follows current security best practices.
