Naturalization is the official term for obtaining citizenship. The more ties you have to Hungary, the sooner and easier you can become a citizen. However, eventually you become eligible even if your only tie is living here; that is when we talk about regular naturalization.
If you were not born a Hungarian citizen but acquired Hungarian citizenship through naturalization, the short answer is: yes, your Hungarian citizenship can be revoked. However, that can happen only under special conditions. If you did everything correctly, and especially if you live in Hungary, you have very little to worry about during a citizenship check.
