How to use the free version on Mac?

I downloaded ProtonVPN on my Android phone and it works fine using the free version without signing in. However, when I downloaded the software on my MacBook I have to sign in. And I can only create an account by selecting a pricing plan. I online that people do use Proton for free on Mac. So my question is: How?

  1. Create a free account: https://protonvpn.com

  2. Login and connect

In order to create an account, you have to choose a payment plan

No you don’t. You can create a free account. There’s a “Get Proton free” button.

Otherwise you can use this URL:
