About Password Generator
Strong passwords are the first line of defense for your online accounts. This generator creates cryptographically random passwords with customizable length and character sets. It also calculates the entropy (randomness measure) and provides a strength rating so you know exactly how secure your password is. All generation happens securely — passwords are never stored or logged.
How to Use
- Set your desired password length using the slider.
- Select which character sets to include: uppercase, lowercase, numbers, symbols.
- Click "Generate" to create a random password.
- Review the strength indicator and entropy value.
- Copy the generated password.

Frequently Asked Questions
How is the password generated?
Passwords are generated using a cryptographically secure random number generator, ensuring true randomness that cannot be predicted.
What is password entropy?
Entropy measures the randomness of a password in bits. A password with 80+ bits of entropy is considered very strong. Each additional bit doubles the number of possible combinations.
What makes a strong password?
A strong password is long (16+ characters), uses mixed character types (uppercase, lowercase, numbers, symbols), and is randomly generated rather than based on words or patterns.
Is my generated password stored?
No. Passwords are generated on the server, displayed to you, and immediately discarded. Nothing is stored or logged.
