To use Badlion Client, you are required to have an account. You can either register a Badlion account or directly log in using your Microsoft account that has a Java Edition Minecraft account linked to it.
In this guide, you will learn how to register a Badlion account. If you do not wish to register a Badlion account, click the "Login with Microsoft" button (it can be seen in the screenshot below).
To register on Badlion Client, you first need to download it from https://client.badlion.net/.
Once you have installed Badlion Client, you must open it and click the "Register your Badlion Account" button.
Add your Java Edition Minecraft account by clicking the "Add Account" button.
Once you have clicked the registration button, you must check your email to finish your Badlion account registration. If you do not see the email, check your spam folder/box or wait a few hours.
If you are having problems activating your Badlion account (e.g. not receiving the registration email), we suggest following the instructions in this help article: click here.
Congratulations, and welcome to Badlion! You have successfully registered on Badlion Client!
