Please add pin protection to the APP

Google Authenticator is a popular way to implement 2 factor authentication for Gmail et other applications like Lastpass.

Since I depend on it for my access, I installed the application on my phone and my Ipad (in case I forgot my phone)l.

My phone is with me most of the time but I often forget my Ipad beside my computer.

It means that at some point someone can gain access to my Google Authenticator apps

That is why I would like to be able to pin protect my Google Authenticator apps. It should be optional.

I know that I can aggressively protect my Ipad or Iphone with a PIN to obtain a similar result but that is not very productive. I would loose a lot of time entering my pin more often.

Either one day Apple enable me to pin protect certain apps and until then, It would be nice if apps like Google Authenticator would include an optional apps pin code protection.
