security - Does official Gmail app use a secure connection?


As simple as that, when I'm using the official Gmail app to access my email account, does it use a secure connection?



Answer



One should be careful to differentiate between the gmail app, and the default mail client.


Gmail App



The Gmail app is the pre-installed app created by Google that can only be used with Gmail. The answer to whether or not the Gmail app is secure requires some understanding of Android app security. This passage from the dev guide explains how developers may connect to an SSL Socket to securely send TCP/IP communications.


Since the Gmail app uses SSL Sockets when sending and receiving mail, all communications are secure [citation needed].


Mail Client


Unlike the Gmail app, the default mail client can be used with any email account, including Gmail. When using this client to send and receive Gmail, an SSL connection must be used. The app is therefore also secure. Google explains how to do this in their help pages.
