Find your Surfshark details

The credentials for the Surfshark service differ from the credentials of your Surfshark account, namely your e-mail and your password. You need credentials for the Surfshark service in order to connect to the VPN via a manual OpenVPN configuration, which is explained below.

Here is how you can get your Surfshark service credentials:

  1. Log in to your newly created Surfshark account and visit the manual connection guide.
  2. Scroll down on this page to see your various location configuration files, as well as your username and password.

You may need to log in before you get to this page. In this case, enter your e-mail address and password and then click Login.

How did it go? Please leave a comment below if I missed something or if everything worked for you. I would love to hear from you!

I found Speedify + Connectify to be one of the easiest ways to make things work instantly and without too much effort. You can use other VPNs, but you still need a way to somehow get your phone into the VPN network and they have set up these two tools to do that.

I used Google Fi from Comber, Ontario to Quebec and had service most of the time, except for Mont-Tremblant National Park, where there is little cell phone reception. If you can, try calling via WiFi apps, otherwise it costs 20 cents per minute when you call home to the United States.
