Netflix is cracking down on account sharing. Sharing Netflix accounts will be subject to a fee in the future.
This is how you can bypass the lock. Netflix itself spoke of almost 100 million users who simply use the accounts of their friends or family and therefore do not pay for them. Since Netflix only wants to use the IP addresses of users in its action against account sharing, it can be created artificially. VPN access can be set up on your own router – technically speaking, this is not a difficulty.
