What makes a password strong?
A strong password typically has at least 12-16 characters and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. The longer and more varied the password, the harder it is to crack. Our tool shows a strength indicator to help you gauge password security.
Is this password generator secure?
Yes, absolutely. Our password generator uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. All password generation happens entirely in your browser - no passwords are ever transmitted to or stored on any server.
Why should I exclude ambiguous characters?
Ambiguous characters like 0 (zero) and O (letter O), or 1 (one), l (lowercase L), and I (uppercase i) can be easily confused when reading or typing passwords. Excluding them makes passwords easier to use while maintaining security.
How many passwords can I generate at once?
You can generate up to 100 passwords at once. This is useful when you need to create multiple accounts or want to have backup passwords ready.
