I assume by checking you mean "not allowed by the person."
Depends on which relation you got to the person. But mostly it is yes, since your compromising their security and personal data. Depending on your country, it is a crime and some places you can go to jail by this crime.
I would suggest you to stop doing this.
If you got the authorization of the person whom your checking for, it would not be a crime.
