Configure VPN Connection on Android (OpenVPN)
Requirement!
To set up the VPN, you need a second factor (abbreviation: 2FA or MFA). This is an additional security layer in addition to your HTW account password. You can set up the second factor using the following guide:
Multi-Factor Authentication
It is strongly recommended not to run any additional VPN clients in parallel!
Step 1: Download OpenVPN from the Google Play Store
Install the OpenVPN client from the Google Play Store.
Step 2: Confirm the EULA
After installation, launch the OpenVPN app and confirm the license agreement (EULA) by clicking "AGREE".
Step 3: Load and select the configuration file
Download the VPN profile from our download portal (you need to log in with your HTW account). Then return to this guide.
To download the VPN profile
After the download: Select the "Upload File" tab in the OpenVPN app, click "BROWSE," and choose the configuration file you just downloaded.
Step 4: Confirm the import
Confirm the import by clicking "OK."
Step 5: Login
In the view, enter your HTW account username & password (without @htw-berlin.de; e.g. s0000001 or amuster) in the “Username” field and click on “CONNECT”.
Step 6: Second Factor
Enter the one-time password (numeric code) generated by your authenticator app in this view. You set up this app using our guide. Then click "SEND."
Confirm any permission requests here by clicking "OK."
Step 7: Successfully Connected
If everything was entered correctly, you will see "CONNECTED" in the OpenVPN app.
When the app is closed, it will continue to run in the background.
NO openVPN possible in eduroam or the HTW network!
In the entire HTW Berlin network (including in the eduroam WLAN), an OpenVPN connection cannot be established (a timeout is displayed in the OpenVPN client).
Its use is mainly intended for outside the university.
Uninstallation of old VPN clients
After completing the installation, we recommend uninstalling old installations of the Cisco AnyConnect program (if you used our old VPN client).
