Features
--------

[](#features)

- Adds an accessible password strength meter beside password fields.
- Password strength is labeled as "Very Weak", "Weak", "Good", "Strong" or "Very Strong".
- Password strength is active on user-facing registration/account password forms and supported ACP user password forms.
- Password strength is scored using one of the available algorithms:
    1. **Complexity** checks for a mix of characters, case, symbols, numbers and length. This can encourage complex passwords, but can score easily cracked passwords like `P@s$w0rd` as strong.
    2. **zxcvbn** calculates how guessable a password is by comparing it to dictionaries and recognizable patterns. This is a more robust strength checker that allows user-friendly passwords that are easy to remember but still hard to guess.
- The zxcvbn algorithm displays localized feedback about weak passwords when available.
- zxcvbn dictionary/feedback support is included for Arabic, Croatian, Czech, Danish, Dutch (Belgium), English, Finnish, French, German, Indonesian, Italian, Japanese, Kurdish, Persian, Polish, Portuguese (Brazil), Romanian, Spanish, Thai, Turkish and Chinese.

Disclaimer
----------

[](#disclaimer)

Password Strength is intended to encourage forum users to choose stronger passwords. It does not guarantee protection against password attacks, and it does not replace phpBB's server-side password validation or password confirmation checks. Password scoring is an estimate, so choose the strength algorithm that best fits your forum.
