How 2 crack Minecraft with PolyMC

Credits: >>383826759

I found out how to use it without Microsoft / Mojang account. There is no need for an extra cracked fork and you only have to do the following once:
>1. Go to the PolyMc folder (In PolyMC -> Folder (menu bar) -> View Instance Folder and then go one up)
>2. Close PolyMc
>3. create an textfile named "accounts.json" (or open it if it already exists) in the folder
>4. paste:

{
"accounts": [
{
"entitlement":{
"ownsMinecraft": true,
"canPlayMinecraft": true
},
"type": "Offline"
}
],
"formatVersion": 3
}

>5. Save
>6. Open PolyMc -> Settings -> Accounts (there is now one "No Profile" account)
>7. Click "Add Offline" and choose some username
>8. Check that new account as active
>9. Delete the "No Profile" Account

Background:
If you do not have any account added, PolyMC will only allow you to create a Mojang or Microsoft account and give you a warning if you want to create an Offline one.
By adding a dummy in its accounts.json file, we fulfill that requirement, so we can add as many Offline accounts as we want and delete the dummy again.
