Do I need ID me for children given years of TurboTax eFilings?

I have filed my taxes with TurboTax for my family for many years (10+), which recently, includes the PIN. Does that mean I am protected from someone else (without the PIN) from fraudulently filing taxes on my name? What about against my kids?

I had two co-workers report today of the challenges they have had because someone obtained the SSN of their kids and filed taxes claiming them as dependents. I'm trying to prevent that, see if I should go for the ID Me, and/or anything else. Note, nothing has happened to me, no divorces, no alternate parents, I am just trying to be pre-emptive to potential identify theft because of my co-workers experience, but wondered if already having years of TurboTa eFiles could prevent that already.
