Some users who created their account with a social log in via Google are facing problems logging in to the MS Word add-on.
They see the following error message:
Please use the following link to reset your password: https://languagetool.org/password/reset. Make sure you're logged out of your LanguageTool account when you want to reset the password.
As soon as you've created a new password, you can log in to the MS Word add-on using that password (not using the Google login).
