Frequently Asked Questions
Why is password length important?
Length is the most critical factor in password security. Every additional character exponentially increases the number of possible combinations, making it much harder for attackers to crack your password using brute-force methods. A 16-character password is generally considered highly secure for modern standards.
Should I use a password manager?
Yes, highly recommended. Password managers generate and securely store complex, unique passwords for all your accounts. You only need to remember one strong master password, rather than trying to remember dozens of complex passwords generated by tools like ours.
What is a passphrase?
A passphrase is a sequence of words or other text (e.g., 'correct-horse-battery-staple') that is long enough to be secure but easier to remember than a random string of characters. Some experts prefer long passphrases over shorter, highly complex passwords.
How often should I change my passwords?
The current recommendation from security experts (including NIST) is to change your password ONLY if you suspect it has been compromised, rather than on a set arbitrary schedule. Frequent forced changes often lead users to create weaker, predictable passwords (like adding a '1' at the end).
Are my generated passwords stored?
No. This tool generates passwords entirely locally in your browser using JavaScript's random functions. No passwords, lengths, or settings are ever sent over the internet or saved on our servers.
