Domande Frequenti
Tutto quello che devi sapere sulla generazione di password sicure
Come vengono generate le password?
Le password vengono generate utilizzando crypto.getRandomValues(), il generatore di numeri casuali crittograficamente sicuro integrato nel browser. Questo garantisce che ogni password sia veramente casuale e imprevedibile, a differenza dei generatori basati su Math.random() che non sono adatti per scopi di sicurezza.
Cosa significa entropia della password?
L'entropia misura la casualita di una password in bit. Si calcola come log2(N^L), dove N e la dimensione del set di caratteri e L la lunghezza della password. Una password con 40 bit di entropia e debole, 60 bit e media, 80 bit e forte e oltre 80 bit e molto forte. Piu alta l'entropia, piu difficile e indovinare la password.
Quale lunghezza della password e consigliata?
Per un buon livello di sicurezza si consiglia una lunghezza minima di 16 caratteri con lettere maiuscole, minuscole, numeri e simboli. Per account critici come banche o email principali, si consiglia almeno 20 caratteri. Per passphrase o chiavi di crittografia, 32 caratteri o piu.
Le password generate vengono salvate o inviate?
No, le password vengono generate interamente nel tuo browser e non vengono mai inviate a nessun server. Nessun dato lascia il tuo dispositivo. Una volta chiusa o aggiornata la pagina, le password non saranno piu recuperabili.
What makes a password strong?
Length above all. Every extra character multiplies the possibilities, far more than swapping a letter for a symbol does. Sixteen characters drawn at random beat eight clever ones by a wide margin.
Where does the randomness come from?
From the cryptographic random number generator of the browser, not from the ordinary one used for shuffling lists. That is the difference between a password that cannot be predicted and one that looks random.
Is the password sent anywhere?
No. It is generated in the page and never leaves the device: nothing is sent to a server and nothing is stored. Closing the page is enough to make it disappear for good.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
