I want to appeal the action taken by moderator. This question was deleted, but I think it was a legit & normal question, and doesn't deserve to be deleted. The moderator has also deleted the answer too. I don't know if that was the reason, but surprisingly to me, he says in a comment that "..The TOTP does not need to be secure on the device..." . I am astonished to hear that from a person in a security-field . So, that means all Top-class security apps (like 1Password, LastPass, WinAuth, and name any serious app, which prove to work oppositely) are unaware/underqualified in security field, in contrary to the moderator, at such level that opposite thoughts/questions are even erased from site. So, I think the opinion that moderator shared (as seen in comment) in the subject is not correct, and moreover, the action to delete the question. I've tried to communicate with him and ask few questions, related to in-details of security apps, but I only repeatedly hear that "I made a rant" (which I absolutely refuse and never admitted, oppositely, I said that was ironic when I called my post a "rant").
Of course, I don't wish to argue with moderator, but I just think the question and answer have not been so bad, that deserved such straightforward deletion, and I wish the question & answer was recovered back. I want another moderator take a look and objectively judge and tell, if that Q/A doesn't have a right to be on SE, and deserved such a targeted deletion, and also mention which action of moderator was mistake - to leave topic open (even he edited the question & answer initially and allowed it to exist) or his later decision to delete it because of a specific comment made later (does a single comment decides the fate of the Q&A itself?)
