REQUEST HOW TO ELIMINATE H_A_C_KER/ LOST PHONE and OTHER USER OTHER THAN YOU PLAYING!

Good Day

As my own experience we users play Coc on multiple device and save our progress thanks to G+.

My request is that supercell should add a password/one-time code verification every major update or one time like the name change. Or a request button requesting a code on mail so that next time i log-in it will need a one time code verification if the user believes he/she was h-a-c-k-e-d or someone using COC other than the user itself.

How does this help? i read many forums about someone other than them are playing their COC with reasons like:

H_A_C_K_E_R_S
Loss Phone
Log-in from acquaintance/relative phone ones and they are totally messing my COC.

Sadly browse as you may all the response i seen so far are sorry.... talk about it.... We cant do anything about it... contact our support.... etc etc.

But some games i have on android phone has this function already "ex. Summoner war arena". they integrate the games to g+ after all it is our google account that is paired with the app upon installing in G play. Our COC is the only one h-a-c-k not our account so if supercell can add this function sending the verification code on our gmails even if its a lost phone, family or h-a-c-ker after update they can no longer log in into our village because they don't know the verification code sent into our emails.Boom Problem Solve!

So please add these function
