Oauth is essintially a different company or enterprise that supplys you with a user's sensitive information that you can use, by validating the information that you give them, and requesting the specifics with your requests and responses between each other. Whenever you see a "sign in with" and then a companys name, that uses Oauth to take youre data with that company, and use your information to supply a different company with for log in purposes. It's a great way to secure data, as whoever request the information, will not actually have the data, only a gerneated token that would need to be verified again with that provider.
