to download them you'll need a GitHub account.

Q: Which mod loaders are supported?
A: Forge, Fabric, NeoForge. Quilt should work too.

Q: Which versions are supported?

Old mod versions (for MC 1.8.9, 1.12.2, etc.) are not supported.

Q: Do I need Fabric API or Quilt Standard Libraries?

Obviously, you do NOT need them for Forge or NeoForge.

Q: Help, I have shared my account with someone! Someone is using my account via In-Game Account Switcher!
A: Read the "Stolen Accounts" page.

Q: I'm using an old version (for 1.8.9/1.12.2) of the mod and it gives me the "SSLHandshakeException" error, how do I fix it?
A: You need to update your Java 8 to a newer build. You can use any Java vendor that you want, there's little to no difference, popular choices:
Eclipse Temurin (Windows,
macOS,
Linux),
Azul Zulu (Windows,
macOS,
Linux),
Amazon Corretto (Windows,
macOS,
Linux).

Q: I'm using Feather/Lunar Client and the mod doesn't work properly (the button doesn't appear, the account list is empty, etc), when you will fix this?
A: These clients break lots of things. Since they are closed-source, we cannot add compatibility with them.
You should ask client developers to fix any issues. Many of this clients have their own built-in account switcher, use it instead.

Q: Can I import/export my accounts from/into a file? Can I use access tokens/cookies to add Microsoft accounts? Will you add this?
A: No. This kind of behavior is either shady or prohibited by Minecraft EULA.

Q: Is this mod open source?
A: Yes. (Licensed
under GNU LGPLv3)

Q: I've found a bug.
A: Report it here. If you are
not sure if this is a bug, you can join the Discord. If you think this bug is
critical enough not to be disclosed publicly, please, report it as described in the
security policy.
