As an adult, you probably need to authenticate yourself in the following situation.

opening a bank account, getting a credit card, getting a mortgage or a loan, buying a flight ticket, signing up for internet service, signing for mobile services, buying a concert ticket and the list goes on.

What's common here is the service provider need to know you are actually the person say it is you and not someone else.

Back in the old days where we apply the service in person, you can take your driving license or passport to authenticate yourself, but with myriad of services now moving online, we need a centralised system that mimic the physical ID.

For a flight ticket I just ID myself at the airport so that's not an issue. For concert tickets I don't need to do this now. For internet service I absolutely don't need that, all they need to know is that I pay.

And mortgage, bank etc I just do on premise of course. These things are rare and important enough to warrant to just go there.
