If you're unable to log in or update your GMX password in @brand, you may need to create an application-specific password.
Steps to Create a GMX Application-Specific Password:
- Log in to your GMX account in a web browser.
- Click on Account and then Security Options.
- Click on Manage application-specific passwords.
- Click on Create new application-specific password.
- Enter a name for the app and click Continue.
- Copy the generated password immediately — it will only be shown once.
- Use this application-specific password when adding or updating your GMX account in @brand.
