I was able to change the language of the reset password prompt using: wixUsers.promptForgotPassword("es"); But then the password reset email is in English, AND clicking the link from that email gives a reset password form in English as well.

@givemeawhisky My site’s language is already in Spanish. Each login page is already in Spanish as well.

No need for multilingual. It’s all Spanish
