Generate strong, secure passwords instantly with our free random password generator online. Create complex passphrases to protect email, banking, and social accounts from hackers. Perfect for boosting online security, preventing brute force attacks, and keeping your data safe.
Entropy: 0 bits
Time to crack:
Traditional Password
Complex strings like Kj7@pL!9xR can be very secure but harder to remember.
Passphrase
Multiple words like correct-horse-battery-staple are easier to remember while still secure due to length.
Which to Choose?
Passphrases are great for memorization, while complex passwords work best when stored in a password manager.
Best Practices
- Use a unique password for each account
- Longer passwords are more secure (12+ characters)
- Include a mix of character types
- Consider using a password manager
- Enable two-factor authentication when available
Password Strength
Password Entropy
Entropy measures password randomness in bits:
- 28 bits: Easily cracked (less than a minute)
- 50 bits: Moderate security (days to weeks)
- 80 bits: Very secure (centuries)
- 100+ bits: Extremely secure (millennia)

Why Strong Passwords Matter
In today's digital world, passwords are the first line of defense against unauthorized access to your accounts. Weak passwords can be easily cracked by hackers using brute force attacks or dictionary attacks, potentially leading to identity theft, financial loss, and compromised personal information.
How Hackers Crack Passwords
Cybercriminals use various techniques to crack passwords:
- Brute Force Attacks: Trying every possible combination until the password is found
- Dictionary Attacks: Trying common words and phrases from dictionaries
- Phishing: Tricking users into revealing their passwords
- Credential Stuffing: Using passwords leaked from other breaches
- Social Engineering: Manipulating people into giving up passwords
Creating Strong Passwords
Follow these guidelines to create secure passwords:
- Use at least 12 characters (longer is better)
- Include uppercase and lowercase letters, numbers, and symbols
- Avoid personal information (names, birthdays, etc.)
- Don't use common words or patterns (like "password123")
- Consider using a passphrase (multiple random words)
Password Managers
Password managers help you:
- Generate and store strong, unique passwords for all accounts
- Auto-fill passwords so you don't have to remember them
- Sync passwords across all your devices securely
- Alert you about compromised passwords
Popular password managers include LastPass, 1Password, Bitwarden, and Dashlane.
Two-Factor Authentication (2FA)
2FA adds an extra layer of security by requiring a second verification method (like a code from your phone) in addition to your password. Enable 2FA on all important accounts like email, banking, and social media.
