Is the Auto-Type feature resistant to keyloggers?
No. The Auto-Type feature has been designed in a way that it’s impossible for target applications to distinguish real keys from auto-typed ones. This on the one hand has the advantage that the feature is really compatible with all applications out there. On the other hand, the auto-typed keys can of course be logged by keyloggers. If you worry about keyloggers, you have to use one of the other methods (drag&drop, copying to clipboard, KeeForm, browser integration toolbar, …).
