Frequently Asked Questions
What makes a strong password?
A strong password is at least 16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special characters. The more character types and the longer the password, the stronger it is. Our generator creates passwords with high entropy to ensure maximum security.
What is password entropy?
Password entropy measures the randomness and unpredictability of a password, expressed in bits. Higher entropy means the password is harder to crack through brute force. A password with 80+ bits of entropy is considered very strong. Entropy is calculated as log2(pool_size ^ length).
Are these passwords generated securely?
Yes. Our password generator uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. This is far more secure than using Math.random(). All generation happens entirely in your browser.
Should I exclude ambiguous characters?
Excluding ambiguous characters (like l, 1, I, O, 0) can make passwords easier to read and type, especially when you need to enter them manually. However, it slightly reduces the character pool and entropy. For maximum security, keep all characters; for readability, use the exclude option.
How many passwords should I generate at once?
You can generate up to 10 passwords at once. This is useful if you want to pick the one you find easiest to remember or if you need passwords for multiple accounts. Always store your passwords in a secure password manager.
