Not “in the future”. The real version of those types of tasks already exists, and has had existing career types for decades now:

computer repair
information technology (IT)
information security

Though those careers have other types of tasks and abilities, too. And, there are programs and features to help people remember or recover their passwords and security questions.

So, there isn’t a place for a specialist in only being a “computer locksmith”, unless maybe you mean a software developer who specializes in designing the authentication aspects of computer programs. But see also the more recent fad for “blockchain” application developers.

We have them now, they’re called hackers.

What the hell is a ‘computer locksmith’? You mean Cybersecurity? Cybersecurity is already a VERY lucrative field to go into. And, pro tip, if you find the right project, you don’t even have to KNOW anything about cybersecurity. It’s a field where personnel are in high demand and they’ll hire anybody JUST to have someone.

I say this, because my project has TWO of them. Two people work as our cybersecurity team, and I’ve talked to them…they both know JACK SQUAT about cybersecurity. They’re one step above ‘moron’ in terms of knowledge about the topic. I’m NOT a cybersecurity expert, and I’ve had to explain to them why they’re wrong multiple times only to be greeted by blank not-understand faces. All they do is push a scan button on our security suite once a quarter and generate a report.

Now GOOD cybersecurity people also exist of course…just saying, they’re not ALL good. Or even minimally competent.
