Frequently asked questions
Are generated passwords stored or transmitted anywhere?+
No. Passwords are generated and displayed entirely in your browser using the Web Crypto API and are never sent to a server.
How long should my password be?+
Most security guidance recommends at least 12 to 16 characters combining uppercase, lowercase, numbers and symbols for strong resistance to brute-force attacks; use the length slider to go higher for especially sensitive accounts.
Can I exclude ambiguous characters?+
Yes, toggle 'Exclude similar characters' to remove characters like l, 1, O and 0 that are easy to misread, which is useful for passwords you need to type manually or read aloud.
Is this safe for generating passwords for important accounts?+
The tool uses crypto.getRandomValues, the same secure randomness source browsers use for cryptography, making it suitable for real account passwords.
Should I use a different password for every account?+
Yes, reusing passwords across sites means a breach on one service can compromise all your other accounts. A password manager paired with unique generated passwords like these is the recommended approach.
Why does the strength meter change when I disable a character set?+
Removing an entire character category (like symbols) shrinks the pool of possible characters per position, which lowers the total number of possible combinations even at the same length, reducing resistance to brute-force guessing.
Can I generate a passphrase instead of a random string?+
This tool generates character-based passwords rather than word-based passphrases. If you prefer a passphrase (several random dictionary words), that's a different generation method not currently offered here.
Does a longer password always beat a more complex one?+
Generally yes — length contributes more to total entropy than adding character types, which is why security guidance increasingly favors longer passwords over shorter ones packed with symbols.
