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:
- Use our random password generator to create strong passwords
- Never reuse passwords across multiple accounts
- Change passwords every 3-6 months for critical accounts
- Use a password manager to store your passwords securely
- Enable two-factor authentication (2FA) whenever available
- 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
