I have made many mistakes in the exchanges and the use of Authenticator. As I use the Google Authenticator mostly through which I can send my transactions and money etc. But in the recent time when I opened my MEXC I forgot my Authenticator that in which Mobile Phone it is present so I mistakenly restore my phone thinking that it can recover my Authenticator. But when I opened it there wasn't any Google Authenticator at all.
So, in this was I lost my 400$. Although this was not a big amount for me in the MEXC Exchange. But loss is always loss. So, my advice for the beginners is to always save their key in their respective dairy through which they can easily recover it.
