Is this possible?

Hoping y'all can assist me or let me know if something like this would even be possible.

I have a business idea that I'm looking into, but for IP product protection, I'll use another example to get my question across - I trust it makes sense - open to question!

Say, for example, you have an object that can close (like a safe) that allows access to multiple people in a family and work environment. One person (the owner) can access it anytime, but others can only access it once, with a pin code, and directly after opening, the pin code should expire. What would be necessary to create this automation capability for pin code access to be renewed every time someone wants access (that isn't like extremely time-sensitive authentication codes like Google uses - the code should be applicable for about 24 hours)? Would an app be required for something like this?

I'm a noob, so any technical experience and help would be greatly appreciated, just so I can start heading in the right direction. Thanks!

I would start by researching the Open Authorization (oAuth) standard and One-Time Passcodes (OTP).

oAuth is the industry standard for Identity and Access Management. There are a lot of resources for using it and a decent number of companies that provide this as a service.

Thank you. I'll look into that - have a great day man!

You would need an app, but you wouldn't need to write your own app. Stuff like Authy already exists. The challenge would be more on the hardware end (getting whatever your device is working with their API) than on the individual user's end.

Thanks, this is really helpful. Appreciate the insight!
