While you are able to login to your account from numerous devices, you are NOT permitted to login to a device that has been previously accessed by a different player's account. Using multiple accounts on a singular device could potentially lead to a lock on the accounts of all player's who have used the device. 

We are strict on this policy simply for the safety of our player's funds and identities. We do not permit multiple accounts on one device in an attempt to ensure players are not using multiple accounts and to lessen the chance of someone having unauthorized usage of your account.
