EFF: “With Gmail’s new design rolled out to more and more users, many have had a chance to try out its new “Confidential Mode.” While many of its features sound promising, what “Confidential Mode” provides isn’t confidentiality. At best, the new mode might create expectations that it fails to meet around security and privacy in Gmail. We fear that Confidential Mode will make it less likely for users to find and use other, more secure communication alternatives. And at worst, Confidential Mode will push users further into Google’s own walled garden while giving them what we believe are misleading assurances of privacy and security. With its new Confidential Mode, Google purports to allow you to restrict how the emails you send can be viewed and shared: the recipient of your Confidential Mode email will not be able to forward or print it. You can also set an “expiration date” at which time the email will be deleted from your recipient’s inbox, and even require a text message code as an added layer of security before the email can be viewed. Unfortunately, each of these “security” features comes with serious security problems for users. It’s important to note at the outset that because Confidential Mode emails are not end-to-end encrypted, Google can see the contents of your messages and has the technical capability to store them indefinitely, regardless of any “expiration date” you set. In other words, Confidential Mode provides zero confidentiality with regard to Google…”
