Rýchla odpoveď
It builds a string from the selected alphabet using secure randomness in the client.
Príklad: 16 characters with upper, lower, digits and symbols is a common default; longer is stronger if you can store it.
Výpočty sa riadia vzorcom na tejto stránke; zaokrúhľovanie a jednotky môžu zmeniť poslednú číslicu. Výsledok berte ako vzdelávací odhad.

Čo táto kalkulačka robí
It builds a string from the selected alphabet using secure randomness in the client.
Pre koho je
Anyone creating a new password who wants the generation to stay on-device.
Ako výpočet funguje
A cryptographically strong RNG picks indices into the allowed character set until the requested length is reached.
Vzorec
Uniform draws from the selected alphabet. No password is derived from your name or the page URL.
Predpoklady
- The browser provides crypto.getRandomValues or an equivalent.
- You store the result in a password manager.
Obmedzenia
- Does not check whether a password has appeared in a public breach.
- A short alphabet reduces strength even at long lengths.
Ako nástroj použiť
- 1Set the length.
- 2Toggle character classes.
- 3Copy the result into a password manager — not into email.
Časté otázky
- 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.
