What makes a password actually strong?
Length matters far more than complexity rules. A 16-character random string drawn from a large character set takes centuries to brute force, while an 8-character password with mixed case and symbols falls in hours. Aim for at least 14 to 16 characters for important accounts, use a unique password per site, and store them in a password manager so you never have to remember more than one master passphrase.
Should I include symbols and numbers, or is length enough?
Both help, but length dominates. Each extra character multiplies the search space by the size of the alphabet, so going from 12 to 16 characters adds many orders of magnitude of resistance. Symbols and digits expand the alphabet and matter most when length is constrained by a site that caps you at 12 or 16 characters. When the site allows longer passwords, prefer length over complexity.
Is a randomly generated string better than a passphrase?
Both can be strong if long enough. A truly random 16-character string from a 90-character alphabet has about 104 bits of entropy, which is plenty. A six-word Diceware passphrase from a 7,776-word list has about 77 bits, which is also strong and far easier to type or memorize. Use random strings for stored credentials and passphrases when you must remember the password yourself.
Is my generated password sent to a server?
No. Passwords are generated entirely in your browser using a cryptographically secure random source - typically the Web Crypto API's getRandomValues. The result is never transmitted, logged, or saved on our side. Closing the tab destroys the value from memory. For maximum safety, copy the password directly into your password manager and avoid pasting it into other untrusted tools or chat windows.
How often should I rotate strong passwords?
Modern guidance, including from NIST, says do not rotate strong unique passwords on a schedule. Forced rotation pushes users toward predictable variations like Password1, Password2, which is worse than leaving a strong password alone. Rotate immediately if there is any sign of compromise, if the service announces a breach, or if you ever shared the password. Otherwise let your password manager keep them indefinitely.
Why does the generator avoid lookalike characters by default?
Characters such as l, 1, I, O, 0 are easy to confuse when reading a password aloud or copying it from a screen. Excluding them slightly reduces entropy but makes the password far easier to enter correctly when you have to type it manually - for instance into a phone or a console. If you only ever paste through a manager you can safely re-enable the full character set.
