Recently, I realized that the public ProtonVPN API was made private, which in turn left the infrastructure in Passepartout outdated for a while. In my opinion, these are reasonable moves by public providers that don’t want their customers to use third party apps, because it would require additional customer support. While I believe that offering API plans for integrating alternative clients or resellers would be a nice addition, it’s absolutely fine if they don’t want to.
Therefore, the ProtonVPN provider will be removed next week from the supported Passepartout providers.
