Creating an account is simple and automatic. All you have to do is open the game.
Seriously, that's it.
When you open the game, it should automatically attempt to log you in using whatever credentials are currently active on your device. For example, if you're opening the game on an Xbox, the game will try to log you in using the Xbox Live account currently active. Depending on your device, it may ask to confirm that you want to log into the game.
For example, if you're opening the game on iOS, a screen may pop up asking you to press "Continue" to confirm logging into the game with your Apple ID. Among Us will not ask you to enter your email address because the account is connected to your device platform profile, which already stores that information (the one exception is trying to verify your age with Kids Web Services, which you can find out more about here).
In the screenshot below, you can see a GREEN light in the top left corner. This means you have a fully verified account, are logged in, and good to play!
Please note that you can only have ONE Among Us account per platform profile. That means only one account per Steam Profile/Xbox Live Account/Google Play Profile/Apple ID/etc. But you can link accounts together and have access to one Among Us account on multiple platforms. For more information on account linking, check out this guide!
Certain errors or settings on your device may prevent you from logging into the game fully:
NOT LOGGED IN/GUEST ACCOUNT
If you see a GREY light in the top corner of your main menu, that means you are not logged into the game. This may be because you are offline, need to log in to your platform service, or need to create an account on your platform.
PARTIAL LOG IN
Likewise, if you see a PURPLE light in the top left corner of your main menu, that means you're only partially logged into the game. You can still play, but until your issue is resolved you'll be limited to Quick Chat Only and assigned a random in-game name (this is done to protect your data privacy). This error is related to account permissions and can be due to a number of issues (usually that something about your information is telling either Among Us or your platform account with Google, Apple, etc that you are a child), but you can still play the game!
AWAITING PERMISSIONS
If you see a CYAN light, that means your account is in the middle of verification and awaiting parental permissions. Complete the process or have your parent/guardian complete the process through Kids Web Services to get your permissions set!
Once whatever is keeping you from logging in is resolved, you should be able to access your regular features again. If you're having problems with the login process, please reach out to support to see if we can help you with the problem!
