Websites are like castles, with large moats around them. You need a password at the gate to get in.
And the average person has to remember 27 passwords!
Remembering passwords is a pain. About 30% of all customer queries are "How do I reset my password?"
So websites found a unique solution: outsource the authentication problem to the ๐๐๐ castles.
---------------------------------------------
Instead of asking users to enter an email and password, websites now ask users to "connect" them with Google for registration.

The user is now authenticated, and a session token can be sent for further auth requests. This process of outsourcing user authentication (technically authorization, since the user authorized you to view their name) is called OAuth.
---------------------------------------------
Third-party sign-in reduces login hesitance, ease of mobile registration, and password reset issues.
It also consolidates data power into a few companies, which know exactly which websites you visited to tailor your ads (Did you register on FirstCry? Let me show you a diaper ad).
