Frequently asked questions
How random are the passwords?
They are generated from crypto.getRandomValues, the browser's cryptographically secure source - the same strength promised by dedicated password managers.
How long should a password be?
Length beats complexity for modern attacks. 16+ characters with all four sets is strong; for critical accounts, 20-32 is better. Long passphrases are also excellent.
Are my passwords stored or sent anywhere?
No. They live in the page's memory only, render briefly, and vanish when the page closes or you navigate away.
Why avoid ambiguous characters?
Characters like O/0 and l/1/I are easily confused when hand-typed or read aloud. Toggle the option to remove them for dictation-friendly passwords.
Should I reuse generated passwords?
Never reuse passwords across sites. Use a password manager that stores unique generated passwords per site.
Is 8 characters enough?
Not for anything that matters. 8 characters is the minimum this tool offers (some legacy systems cap at 8); prefer 18-32 wherever the site allows.
Why should I use a generated password instead of one I invent myself?
Humans create predictable patterns based on words and dates that dictionary attacks easily crack. Random cryptographic passwords resist brute-force attacks.
Can I exclude ambiguous characters like 0, O, l, and 1?
Yes. You can toggle the "Exclude ambiguous characters" setting so passwords are easy to transcribe without visual confusion.
