Sounds like modifiers aren't being held. Options > Send Mode Settings > Uncheck "Clear Modifiers before executing hotkey."

Though "auto-login" shouldn't require any manual typing at all. I explain a full auto-login section of script here. As I say in that thread, I don't automatically send the login information as soon as I launch, I just have it filled in and manually log them in one at a time to deal with patching and authenticator prompts.
