Security experts recommend at least 16 characters for generated passwords. Each additional character exponentially increases cracking difficulty. For high-security accounts like banking and email, use 20 or more characters. Passphrases of 4 or more random words are equally secure and easier to type on mobile.
Reputable password generators like Bitwarden generate passwords locally using the Web Crypto API, which provides cryptographically secure random numbers. The password never leaves your browser. Avoid online generator websites that could potentially log generated passwords on their servers.
Both are secure when properly generated. Random passwords with 16 plus characters and mixed character types are strongest for automated logins. Passphrases using 4 to 6 random dictionary words are easier to remember and type manually. Use passphrases for your master password and random passwords for everything else.
A great password generator tool balances powerful features with minimal permissions. It should do its job well without requesting access to data it does not need. Look for active developers who publish regular updates, a transparent privacy policy, and a strong track record in the Chrome Web Store.
