How to disable VPN before login on macBook Air 2017

Hi guys,

I have a macBook Air 2017 (A1466) that I didn't used for a long time.

Now, I forgot my password to log in, so I tried to do the password recory.

But now it says it can't connect to the apple ID-server.

I have tries almost everything I could find on the internet.

But what I'm guessing... I sometime used HideMyAss VPN provider.

Now, I think the "kill switch" or the VPN-settings are still active...

Therefore I can't login and reset the password.

Is there any way to disable those settings BEFORE login?

As the most tutorials only speaking about changing after logged in...

Thanks in advance!
