Frequently Asked Questions
Common questions about the free strong password generator — randomness, privacy, character sets, and strength.
How does the password generator work?
Choose a length and which character types to include, then click Generate. The tool builds a random password using your browser's cryptographically secure random number generator (the Web Crypto API), ensuring at least one character from each enabled set is present before filling the rest of the length and shuffling the result.
Is the password generator free to use?
Completely free — no sign-up, no downloads, no limits. Use it as many times as you like on any device.
Are my passwords sent anywhere or stored?
No. Every password is generated entirely in your browser. Nothing is sent to a server, logged, or saved anywhere — not even temporarily. Close the tab and the passwords are gone.
How random are the passwords?
They use the cryptographically secure random generator built into your browser (window.crypto.getRandomValues), not the basic Math.random() function. This is the same source used by secure applications for key generation and is genuinely unpredictable.
What makes a password strong?
Strength comes from length and the size of the character pool. The tool shows a strength meter based on entropy — measured in bits — which reflects the total number of possible password combinations. More bits means more combinations, which means harder to guess. Passwords above 60 bits are considered strong; above 80 bits are very strong.
Can I include or exclude symbols and ambiguous characters?
Yes. Toggle uppercase, lowercase, numbers, and symbols independently. You can also turn on the "Exclude ambiguous" option to remove characters that look similar — I (capital I), l (lowercase L), 1 (one), O (capital O), 0 (zero), and o (lowercase o) — making passwords easier to type or read aloud without mistakes.
How long should my password be?
Most security guidelines recommend at least 12–16 characters for general accounts and longer for sensitive ones. The strength meter gives you a live entropy reading so you can see exactly how strong each length is. For most purposes, 16 characters with a full character set gives over 100 bits of entropy — considered very strong.
Can I generate several passwords at once?
Yes. Set the "How many" field to up to 10 and click Generate. All passwords appear in a list, each with its own Copy button, so you can pick the one you like or use different ones for different accounts.
Does it work offline?
Once the page is loaded, passwords are generated entirely in your browser with no server connection needed. If your device goes offline mid-session the tool continues to work normally.
Does the password generator work on mobile?
Yes. The layout is fully responsive with easy-to-tap toggles and a one-tap Copy button. It works on phones, tablets, and desktops without any installation or sign-in.
