As a remote accredited degree candidate (pre-pandemic so I did it before it was cool) the only alternative to Proctorio was finding an actual proctor in my area who was subject to approval by my university and who I would have to pay to sit and watch over me. Every exam was a multi-week hassle that I had to coordinate with the added stress of last minute cancellations. I much prefer Proctorio. Yeah, it’s intrusive for about 2 hours but then you can close it and go on with your life. Not really a big deal.
