The plugin doesn't support too many languages

[salmanm2003]

We are using this plugin across our journals (3.4.0-10), which operate in multiple languages. However, the plugin doesn’t support all OJS languages, resulting in unreadable error messages for some users.

Good point. Looks like we have English, Portuguese, and Turkish. If you have the language skills to add more, the translation files are super easy to work with. For example, here's the English one: https://github.com/ulsdevteam/pkp-betterPassword/blob/master/locale/en/locale.po A translation would involve just switching the text on the msgstr lines to the appropriate translation if you would ever want to submit a PR.
