Secure Password Generator - Create Strong Random Passwords

Our free online password generator creates highly secure, random passwords instantly. Unlike other tools, your passwords are generated locally in your browser - never transmitted over the internet for maximum security protection.

Why Use a Random Password Generator?

In today's digital world, strong password security is essential. Weak passwords are the #1 cause of data breaches and account takeovers. Our tool helps you:

• Create uncrackable passwords that resist brute force attacks
• Generate unique passwords for every account
• Avoid common password mistakes that compromise security
• Meet password complexity requirements for any website

What Makes a Password Strong?

Password strength is measured by how resistant it is to guessing or brute-force attacks. Key factors include:

• Length: Longer passwords are exponentially harder to crack (12+ characters recommended)
• Complexity: Mix of uppercase, lowercase, numbers and special characters
• Unpredictability: Avoid dictionary words, names, dates or patterns

Password Security Best Practices

Follow these password security tips to protect your accounts:

1. Use our random password generator to create strong passwords
2. Never reuse passwords across multiple accounts
3. Change passwords every 3-6 months for critical accounts
4. Use a password manager to store your passwords securely
5. Enable two-factor authentication (2FA) whenever available
6. Avoid personal information like names, birthdays or addresses

Understanding Password Entropy

Our tool calculates password entropy - a mathematical measure of unpredictability:

• 60+ bits: Strong password (resistant to brute force attacks)
• 40-59 bits: Moderate strength
• Below 40 bits: Weak password (vulnerable to cracking)

For reference, an 8-character password with just lowercase letters has only 37 bits of entropy, while a 12-character mixed password can have 80+ bits.

Common Password Mistakes to Avoid

Never use these types of weak passwords:

• Sequences like "123456" or "qwerty" (top hacked passwords)
• Dictionary words or common phrases
• Simple substitutions like "P@ssw0rd"
• Personal information hackers can easily find
• Short passwords under 8 characters
