Extra security + login history

[buddhabomber]

In general, I have been brainstorming an idea for another layer of security for the game to block or deter another user from using a Clash account. The reason that I am thinking of blocking someone from using this account is because of the link account function / save game data on another device after logging into it. Unfortunately this has happened to one of my accounts, the town hall 10, in which someone saved its data to an Apple ID/Gamecenter that I did not make nor use (I am purely an Android user, never once owned an Apple device.) I know this because I have did the 'dance' with Google and did a reset on the credentials to the G+ account but that user still occasionally logs in and to spend my gems that I have bought or just suck at war.

Here are my ideas:
1) extra password function to log into the Clash account. You can make it optional to users. Although that wouldn't be much of a benefit but the most important function is the hint in which I can put "send me an email @ blahblahblah@gma...." or "send me a kik message"

Although the this password option is already redundant to the G+ and Apple iD thingy so I highly doubt it will work. *Edit: I meant Game Center, not Apple ID. I do not use apple and the system it uses until recently.

2) Log in history in the settings/options. I do not know how much information Supercell receives per app but if a log in history with dates/time (and hopefully IP address/general location) will be beneficial for this idea. In my logic, if someone, like myself who owns the account, seeing this information is useless to me but seeing another person's details, possibly the person's details is great. I also have a feeling this breaks some kind of rule in private information and what not. Of course, that other person can also see that information so it is a double edged sword.

Extra idea 3) see the list of connected users / linked devices and have ability to remove that device. I think this is a better idea but the idea is hard to implement. I think the password function will be more beneficial here. Removing it from a device will be password protected so that the other user won't be able to remove the original user.

- Thanks for the read.

I don't think this is really an issue right now... If it becomes an issue this may be implemented

This is an issue

Nvm, this Idea could be helpful in some way.

That's... not really an issue. Not a big one at least.

It may not be a major issue but it is there and it is bugging the hell out of people. Especially the ones who actually spent money to support this game or to improve their base only to have some random person who knows nothing about clash or the account to waste the gems/resources on something the user did not plan on upgrading.
