Strong Password Generator

Strong password generator free – Simply adjust the length slider (8-64 characters), select which character types to include (uppercase, lowercase, numbers, symbols), and your password is generated instantly. Click "Regenerate Password" for a new one. No software needed .

A strong password should have:

• Length: At least 12-16 characters (our generator supports up to 64)
• Character variety: Mix of uppercase, lowercase, numbers, and symbols
• Randomness: No predictable patterns or dictionary words
• High entropy: More bits = harder to crack (80+ bits recommended)
• Uniqueness: Different password for every account

Our generator creates cryptographically random passwords .

Absolutely! Secure password generator free – 100% free forever. No hidden fees, no premium plans, no credit card required. Free password creator tool with unlimited usage. No watermarks, no ads, no sign-up needed .

Password entropy measures how unpredictable a password is. Higher entropy means harder to crack:

• 40-60 bits: Weak – can be cracked in seconds/minutes
• 60-80 bits: Moderate – could take weeks/months
• 80-100 bits: Strong – thousands to millions of years
• 100+ bits: Very Strong – "Multiple Universes" lifespan

Our tool shows entropy in bits and estimated brute-force time .

Our cryptographically secure password generator uses the Web Crypto API (`window.crypto.getRandomValues()`). This is the same technology used for secure web communications and is considered cryptographically strong for password generation. It's not pseudo-random – it's truly random .

Recommended password lengths:

• 12-16 characters: Good for most accounts (with all character types)
• 20+ characters: Excellent security, recommended for critical accounts
• 30+ characters: Maximum security – "multiple universes" strength
• Minimum: 8 characters (our generator starts at 8)

Longer passwords with mixed characters are always stronger .
