Georgia Tech's Online Master of Science in Computer Science (GA Tech OMSCS) is really good about letting you go as fast or as slow as you want. If you are sufficiently motivated (and life circumstances permitting, granted), it's very doable as a nights and weekends type of thing.
I did it over 5 years and it would consume all my free time during crunch periods. Definitely make sure your family is supportive - it’s like having a second part time job with occasional overtime.
Having said that - I believe many companies view OMSCS as a strong signal. It’s a difficult degree with high drop out rate.
I think you had to use the proctoring software. Some people had a dedicated USB stick and would just boot onto that for exams specifically. TAs have to review any flagged exams.
I'm pretty sure it's required for the degree's accreditation. Unfortunately, there is always a small percentage of people who will cheat if they can get away with it.
