How to password protect an app

1Godknows

Hi,
I want to develop a software but do not want the end user to distribute it to others without the others purchasing it from me. In other words, I want a suggestion as to how I could limit a particular software solution to just one user and whenever a third party wants to use the same software [even though they collect the Password from the other user] they shouldn't be able to use the software until they purchase that same software [that obviously] has a different password.

Thanks for reading this question and for the swift response in advance!

This post and the associated tags are a bit confusing. Are you trying to host flarum, sell an extension, or is this not related to flarum?

webeindustry Doesn't look related to me at all.

I was wondering if I could get assistance.

What is the programming language this "software application" is written in? Some additional information would really help us help you without trying to make annoyingly useless assumptions here and there.

luceos Thanks for the good concern you have showed. It Is actually a Java-based program. Thanks for the reliable feedback in advance!

Sounds like a license key. I'm sure someone has written a library in Java for that, you only need to look for it and integrate it into your program.

Likely, it would need to phone home (via the web) to make sure the license key hasn't been used already. Or you could use an authentication scheme (username/password) to use on the web and for any web-based actions.

jordanjay29 Thanks! But what if it is a standalone executable file: will I still demand internet connection?

1Godknows That's up to you. You might want to take to stackoverflow or another tech question site to answer that. You might find some older developers floating around who still remember the tricks used in the 90s when DRM was a thing but they couldn't rely on someone having an internet connection.
