How it works
Choose settings that fit the account
Start with the account’s length and character rules. Each selected character type appears at least once. You can exclude look-alike characters (0O1Ilio) or punctuation that is awkward to type. Generate a new password after any change.
Use a new password for every account and save it in a password manager. The strength estimate checks common patterns, but it does not calculate exact entropy or guarantee safety. Short passwords remain risky even when they mix several character types.
