How to Use the Password Generator
Set your desired length (8–64 characters), choose which character types to include, and click Generate. The password is created locally using cryptographically secure random values — it never leaves your browser.
What Makes a Strong Password?
Strength = Length × Character Variety × Randomness
A 16-character password using all four character types has over 95¹⁶ possible combinations — roughly 10³¹ options. At a billion guesses per second, brute-forcing it would take longer than the age of the universe.
Password Strength Reference
| Length | Combinations | Time to Crack* |
|---|---|---|
| 8 chars | ~6 quadrillion | Hours |
| 12 chars | ~542 sextillion | Centuries |
| 16 chars | ~4 vigintillion | Billions of years |
| 20+ chars | Astronomical | Effectively uncrackable |
*Estimated at 1 billion guesses/second with all character types.
Frequently Asked Questions
How do I create a strong password?
Use at least 12 characters, mix uppercase, lowercase, numbers, and symbols. Avoid common words, names, and sequences. This generator creates random passwords that are extremely difficult to crack.
What makes a password secure?
Length and randomness. A 16-character random password has over 95^16 possible combinations — billions of years to brute force. Avoid dictionary words, personal info, and reused passwords.
Should I use a password manager?
Yes. A password manager lets you use unique, strong passwords for every account without memorizing them. Generate a strong master password, then let the manager create and store the rest.
How long should my password be?
Minimum 12 characters for most accounts; 16+ for sensitive accounts like email and banking. Each additional character exponentially increases security.
Is this password generator safe?
Yes. Passwords are generated entirely in your browser using JavaScript's crypto.getRandomValues(). Nothing is sent to any server, stored, or logged.
What are special characters?
Special characters include symbols like !@#$%^&*()_+-=[]{}|;:',.<>?/~`. Including them dramatically increases password strength.
