Setting up a Supercell ID is free and easy, and there are no passwords: on login, a fresh verification code is sent to you. No more memorizing passwords!
Registering a Supercell ID for all of your game accounts is the best way to switch between them. Just remember to tick the box "Remember me on this device" and you'll be switched between your accounts seamlessly. Not even verification codes are required!
To sign up for a new Supercell ID or log in with an existing one, head on to the game’s Settings.
Then tap the blue Supercell ID button in the bottom of the screen to get started.
On the next screen, select either LOG IN or Register Now depending on whether you're a new or returning user
Once you select one of those two options, simply follow the on-screen instructions and that's it!
To use the same Supercell ID for saving progress in another Supercell game, simply "Log in" with your Supercell ID email address in the other game.
