Why do some programs create an internal frame asking for a Google mail password?

Question

Windows

Have you noticed more than once that programs require that they enter data from the Windows password and mail? IS THIS ALL LEGAL?
This is some kind of technology, but I don’t understand at all how they thought of it so that some left-wing developer would hack my mail.


PS I want to study how an 8-bit Computer works, from microcircuits to OS with assemblers, which **** is the only simulator where it is, this is a game for 5 year old children.

Minecraft is a Microsoft product (since recently). And this "internal frame" is AOuth2 authentication.
This technology allows you to log in through a shared account in third-party applications. It allows you not to resort to direct transfer of login and password to third-party programs. This "frame" is the browser. Built-in browser with an open page of a real authorization site (although it’s not necessary, but that’s about something else).
After authorization, a third-party program gets access to some data of your account - login, name. In general, the rights are configured. But, as a rule, third-party programs only need to identify you. Those. just your mail (not letters, but the name).
So it's time to calm your paranoia and start developing. Knowledge is power.
