How to Create Strong Passwords
Strong passwords are your first line of defense against cyber attacks. Our password generator creates cryptographically secure random passwords that are virtually impossible to crack.
Password Security Best Practices
- Length Matters Most: Use at least 16 characters for important accounts
- Use All Character Types: Mix uppercase, lowercase, numbers, and symbols
- Avoid Personal Information: Don't use names, birthdays, or common words
- Unique for Each Account: Never reuse passwords across different sites
- Use a Password Manager: Store passwords securely, don't write them down
- Enable 2FA: Add two-factor authentication for extra security
Understanding Password Strength
Weak (Red): Can be cracked in minutes. Under 8 characters or using simple patterns.
Medium (Yellow): May take days to weeks to crack. 8-12 characters with limited character types.
Good (Blue): Takes months to years to crack. 12-16 characters with multiple character types.
Strong (Green): Effectively uncrackable. 16+ characters with all character types enabled.
What is Password Entropy?
Entropy measures password randomness in bits. Higher entropy means stronger security. A 16-character password with all character types has ~95 bits of entropy, making it computationally infeasible to crack.
Common Password Mistakes
- Using dictionary words or common phrases
- Simple patterns like "123456" or "qwerty"
- Personal information (names, dates)
- Short passwords (under 8 characters)
- Reusing the same password everywhere
How Our Generator Works
We use JavaScript's cryptographically secure random number generator (crypto.getRandomValues) to ensure true randomness. Your generated passwords are never sent to our servers or stored anywhere.
