How can you know the browsing history of another device without taking their device from them?

Unless you were able to install something like a key logger or some kind of software that monitors what people do then I don't know if you can actually do that.

 

You need a filtering&accountability software. I use CovenantEyes. Here is the link: https://www.covenanteyes.com/. I know there are others if its too pricy.

 

Is nobody even going to consider the blantant breach of privacy that's implicit in this question?

 

Who are you trying to spy on?

 

What you need is some fucking help, not an ability to spy on people.

 

Okay I have one way. From a fellow no life spy to another.
If you have access to their Gmail account (Google account) lets say on a computer you both share.
You can enter a place called "MyActivity" (Just google it) once you're there you will find out a lot of history that google cached up for years even those you thought you deleted.

Matter of fact if you're brave enough go and try it on your own account. You will see a lot of pages you thought you deleted.

 

I could be wrong but I think you can check the router itself. That’s probably how my dad caught me when I was a kid
