Question 1

How secure are the passwords generated by this tool?

Accepted Answer

Very secure. The password generator uses the browser's built-in cryptographic random number generator (window.crypto.getRandomValues), which is designed for security-critical applications. All password generation happens locally in your browser with zero data sent to any server. With a 16-character password using all character types (uppercase, lowercase, numbers, symbols), there are approximately 10^30 possible combinations — effectively impossible to brute force.

Question 2

What makes a password 'strong'?

Accepted Answer

A strong password has three key properties: sufficient length (at least 12 characters, ideally 16+), a mix of character types (uppercase, lowercase, numbers, symbols), and randomness that makes it unpredictable. Our strength indicator evaluates passwords based on these factors. Short passwords with only lowercase letters are considered Weak, while long passwords with all character types are rated Very Strong.

Question 3

Should I exclude similar characters like '1' and 'l'?

Accepted Answer

Yes, especially if you will be reading or typing the password manually. Characters like 1 (one), l (lowercase L), I (uppercase i), 0 (zero), and O (uppercase o) are easily confused in many fonts. The 'exclude similar characters' option removes these ambiguous characters from the generated password, making it easier to read, share verbally, or type without errors while still maintaining strong security.

Question 4

Can I generate multiple passwords at once?

Accepted Answer

Yes. Use the password count slider to generate between 1 and 10 passwords at a time. This is useful when you need to create passwords for multiple accounts, generate temporary credentials, or want to pick your favorite from several options. Each password is independently generated with full randomness.
