That is indeed the case. It’s good to know it’s possible, but custom.
Also since I did not know that a user hitting reply would skip the login dialog depending on implementation, that will alleviate a lot of my concerns in the first place. That is the major barrier to entry that I want to avoid, and I’m glad that it can be implemented.
Of course the data nerd in me wants the ideal version, and it’s possible we might aspire towards that. Knowing it’s possible for now is good enough. Thank you once again everyone for your time.
