How does the process work if I want someone to take my test on my behalf?

I’ve been seeing a lot of discussions lately around the idea of hiring someone to take my exam for me, and I’m genuinely curious — how does the whole process work? With everything being online these days, it seems like there are services that actually help with taking tests or quizzes on your behalf.

I came across MyAssignmentHelp, and they claim to offer secure and confidential online exam assistance. Has anyone here used their services? How do they ensure privacy and authenticity when logging in to take an exam? And what about technical requirements — do I have to share my login details, or do they use remote access?

Here’s the page I found for reference:

I’d love to hear from anyone with experience. Is it safe? How do they match the right expert to your subject? Any tips or red flags to watch out for?
