This is probably the best remote access management utility
This is probably the best remote utilities out there. For someone who just wants to access 1 or 2 computers (it allows 10), it's a totally free tool. Something rarer and rarer each day. It has a host/server component and a viewer which you use to access your hosts. You can even have your own server to generate a unique ID instead of trusting the company server, and as a plus, MFA can be used also to access your hosts (I use Authy for this purpose). The connection is stable, and features like file transfer and full management are available. It's indeed a great tool that I've been using for more than 4 years now.
