Yes. It is possible to do this. There are many spy apps, for example, that allow you to see the content of someone’s Instagram account freely once they’ve been installed on the target device. These apps remain hidden and operate behind the scenes. However, you need to exercise caution. Hacking an Instagram account might be for a good reason — like protecting your child from grooming or exploitation, or for suicide prevention — but it is seen as unethical in romantic relationships that rely on trust. Be wary that even if your reasons are good, if you use illegal practices for hacking Instagram accounts, you could end up in trouble with the law. This is unlikely to happen, however, if you’re a parent trying to protect your child.
