Strong Password Generator
Create unbreakable passwords with high entropy. Mix characters, symbols, and numbers to generate passwords that take trillions of years to crack.
What Makes a Password "Strong"?
1. Length is Key
Length is the most critical factor. A 16-character password is exponentially stronger than an 8-character one. Every extra character makes it thousands of times harder to crack.
2. Character Diversity
Strong passwords use a mix of uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special symbols (!@#$). This maximizes the possible combinations.
3. True Randomness
Humans are terrible at being random. We use patterns like keyboard rows (qwerty) or birthdays. A machine-generated password has zero patterns, making it impossible to guess.
4. High Entropy
Entropy measures unpredictability. A strong password should have at least 60 bits of entropy. Our generator can create passwords with over 100 bits of entropy.
Strong Password FAQ
How long should a strong password be?
We recommend at least 16 characters for important accounts like banking and email. For maximum security, aim for 20+ characters. Our generator supports up to 128 characters.
Are special characters necessary?
While length is most important, adding special characters significantly increases password strength by expanding the character set. We highly recommend including symbols.
How can I remember a strong random password?
You shouldn't try to memorize complex random passwords. Instead, use a secure password manager to store them. This allows you to use unique, strong passwords for every account while only remembering one master password.
