Clash of Beasts allows you to secure your game account by associating it with an email address on the game settings. Once you have added your email address, you will receive a One-Time-Password (OTP) on this email address. Enter the OTP in the game settings to verify the connection. After the account is verified, any game progress will be tied to this email address, which allows you to change your device or play on multiple devices.
You can manage your account in the game settings or on this platform if you have forgotten your email address connected to your account, if you want to change your email address or unlink your email address that is associated with your game account.
