To make a second Brawl Stars account, start by getting a new email address that isn’t linked to any Supercell game.
Next, open Brawl Stars on your device and complete the in-game tutorial. This step is necessary to access the main game features.
Once the tutorial is done, go to the in-game settings menu. Here, you will find the ‘Supercell ID’ option; tap on it and choose ‘Create New’.
Follow the prompts to register your new account using the new email address you created earlier. This will set up a new Supercell ID linked to the new email.
Finally, link this new account to the new Supercell ID. This way, you can easily switch between multiple accounts on the same device and experiment with different strategies without affecting your main account.
