Connect with a cookie on battle.net launcher
- Ask you for a cookie, encrypt it like battle.net does, then overwrite all values in "HKEY_CURRENT_USER\SOFTWARE\Blizzard Entertainment\Battle.net\UnifiedAuth" (these values are only useful for auto-login)
- Make sure that you are logged in with "Keep logged in" option on battle.net.launcher, otherwise the program won't be able to find the value to overwrite, since battle.net remove it when you are disconnected
- If it still doesn't work, open an issue
