I was talking in regards to your question about the account being deleted in the event that you reinstall the app Steve.

If your father's account was created via the "Play as Guest" option, as long as you chose that log-in option it will simply start up the game.


BUT since you are talking about a password I believe that your father already has his Top 11 account linked with one (or more) of the social networks that I mentioned earlier.

If you are having issues logging in the Top Eleven account, may I suggest that you check the Facebook and Game Center/Google+ (Depending on the device) apps on the device to see if the proper accounts have been logged in.
