It is necessary that you protect your identity from being stolen by anyone. Stolen in a sense that they can be used by someone else and they can claim as you. If that happens then there are lots of things that you will be limited from doing, just like making even simple sign ups. Identity is a very serious thing that must be protected at all times and must not be treated as a very simple thing. Protecting your identity means protecting your credibility.
You can start doing some identity protection by doing some simple things like making your personal details in private. Doing so limits anyone to see your full details and so as preventing them using it. There are other ways like asking the help of some professionals like LifeLock. Actually my friend is the one who told me about this. He told me that there are also some good reviews like a LifeLock Review that I can read to find out more about them. You can even Compare LifeLock to other services to find which one is suited for you. It is a nice thing to imagine that nowadays there are still many good hearted people who are ready to help someone.
