Why does any office create two accounts on office laptops? One on employee name and another on admin/office/company name. What is the purpose of it?
It is so that support can access your computer without needing to sign in on your profile. They may need to do this for any number of reasons, troubleshooting, software installation, updating etc,.
It's routine in many networks, particularly those where normal users do not have full admin rights to their machines. But a good idea even when they do, user profiles can become corrupted creating issues signing in and a host of other potential problems which can much more easily be fixed if there is an existing local profile which can be used.
That is also how I set up my personal machines - for normal use admin level access is not necessary.
This limits the errors I can make as an “ordinary” user and if I need to install something I just enter the admin password when asked.
One for you. one so they can log in if you die.
And update software.....
Just use your mobile phone for things you don't want them to see.
