Choose length and character classes. The generator draws from the browser’s cryptographic random source when available.

Pikavastaus
It builds a string from the selected alphabet using secure randomness in the client.
Esimerkki: 16 characters with upper, lower, digits and symbols is a common default; longer is stronger if you can store it.
Laskenta noudattaa tällä sivulla kuvattua kaavaa; pyöristys ja yksiköt voivat muuttaa viimeistä numeroa. Käsittele tulos opetusarvioina.

Mitä tämä laskuri tekee

Kenelle se on
Anyone creating a new password who wants the generation to stay on-device.
Miten laskenta toimii
A cryptographically strong RNG picks indices into the allowed character set until the requested length is reached.
Kaava
Uniform draws from the selected alphabet. No password is derived from your name or the page URL.
Oletukset
- The browser provides crypto.getRandomValues or an equivalent.
- You store the result in a password manager.
Rajoitukset
- Does not check whether a password has appeared in a public breach.
- A short alphabet reduces strength even at long lengths.

UKK
- Do you store the password?
- Generation is client-side. We do not need the password to render the page.
- Is longer always better?
- Length helps, but a tiny character set or a reused password still fails.
