What Makes a Strong Password?

A strong password is long, random, and uses a mix of character types. Length is the most important factor - every extra character makes a password exponentially harder to crack. A 16 character random password using all character types would take billions of years to crack by brute force.

Avoid using real words, names, dates, or keyboard patterns like qwerty or 12345. These are the first things password cracking tools try. A truly random password generated by this tool is far stronger than anything a human would create.

Frequently Asked Questions

Are these passwords safe to use?

Yes. Passwords are generated entirely in your browser using the Web Crypto API. They are never transmitted to any server and are not stored anywhere. Each password is cryptographically random.

How long should my password be?

At minimum 12 characters for regular accounts. Use 16 or more for important accounts like email and banking. For encryption keys and API secrets use 32 characters or more.

Should I use a password manager?

Yes, always. A password manager lets you use a different strong random password for every account without having to remember them. Bitwarden is free and open source. 1Password and Dashlane are popular paid options.
