Email app passwords · GMX Create a GMX
Create a GMX
application-specific password.
GMX ships with POP3 and IMAP switched off, and if you use two-factor authentication it also needs an application-specific password. Miss either and your mail app just fails to sign in, with no useful error.
Applies to gmx.net, gmx.de, gmx.com, gmx.ch addresses.
Step by step
How to create your application-specific password.
- Sign in at gmx.net in a desktop browser (the mobile view doesn't show these settings).
- Click the icon with your initials in the top menu, then E-Mail-Einstellungen (email settings).
- Under E-Mail empfangen → POP3/IMAP, switch on POP3- und IMAP-Zugriff erlauben and complete the slide-the-symbols security check.
- If you use two-factor authentication, continue: open the initials menu again and choose Account verwalten to reach the GMX Kundencenter.
- In the sidebar choose Login & Sicherheit, scroll to Anwendungsspezifische Passwörter verwalten and select Neues Anwendungsspezifisches Passwort erstellen.
- Name it, choose Weiter, and copy the password — it is shown exactly once.
- Use it in BlueMail in place of your GMX account password.
Worth knowing
- GMX switches POP3/IMAP access back off automatically after a long period without use — this is the usual reason a mail app that worked for months suddenly stops.
- Switching two-factor authentication on can also reset that toggle, so re-check it if sign-in starts failing.
- Watch the outgoing server name: GMX uses mail.gmx.net, not smtp.gmx.net. International gmx.com addresses use their own hosts (imap.gmx.com, mail.gmx.com).
Using it in BlueMail
