Frequently Asked Questions
How do I create a strong password?+
Use a length of at least 16 characters and mix uppercase letters, lowercase letters, numbers, and symbols. This generator does that for you automatically using cryptographically secure randomness, so each password is unpredictable and hard to crack.
Are these random passwords actually secure?+
Yes. Passwords are generated with the browser’s crypto.getRandomValues API, the same cryptographic randomness used for encryption keys. We use unbiased rejection sampling so every character is equally likely — we never use the predictable Math.random function.
Is the password generator free and does it require sign-up?+
It is completely free with no account, no sign-up, and no limits on how many passwords you can generate.
Are my generated passwords sent to a server?+
No. Every password is created entirely inside your browser and never leaves your device. Nothing is transmitted, logged, or stored on our servers, which makes it safe for generating real, sensitive credentials.
What does "exclude ambiguous characters" do?+
It removes look-alike characters such as O, 0, l, 1, and I that are easy to confuse when typing or reading a password aloud. Enable it when you may need to enter the password manually.
