Google Confirms Gmail End-To-End Android And iPhone Email Encryption

Google has announced that, with immediate effect, users of Gmail on both Android and iPhone will be able, for the first time, to read and compose end-to-end encrypted emails without the need for any additional apps or tools. This is a monumental move forward in terms of privacy and security for users of the world's most popular email platform. Unfortunately, the advance is not being offered to all 3.5 billion users. And that's the catch. Here's what you need to know.

Google Brings Gmail End-To-End Encryption To Your Smartphone—If You Meet The Criteria

It's been quite the week for big Google privacy and security announcements. First, I reported how the technology giant was introducing new 2FA bypass attack protection for users of the Chrome browser on the Windows platform, and now Google has confirmed it is introducing end-to-end encryption for Gmail users on Android and iOS.

This will, sadly, not impact as many people as the Chrome for Windows update. That's because, Google said, the long-awaited and much-needed encryption feature is only available to Enterprise Plus license holders, and even then, only those with the Assured Controls or Assured Controls Plus add-on.

Regular readers will recall that I first dropped news of Google's rollout for Gmail end-to-end encryption in an October 2026 report. This new announcement, however, takes things even further. "For the first time, users can compose and read these E2EE messages natively within the Gmail app on Android and iOS," Google confirmed . "Users with a Gmail E2EE license can send an encrypted message to any recipient, regardless of what email address the recipient has."

In other words, eligible organizations that use Gmail client-side encryption will now be able to preserve privacy and security controls without worrying about the hassle of exchanging keys or being required to use additional custom software.

Google explained that if a recipient uses the Gmail app, then the encrypted message is delivered as any other typical email threat directly into their inbox. If they don't have the Gmail app, however, the message can be read seamlessly and securely, "in their own native browser, ensuring that all users have a simple and secure interface, regardless of their email service or device."

Now, if only the same level of privacy and security could be applied to all Google Gmail users, including consumers, then maybe I would be able to recommend it to more people. As it is, I will stick to recommending Proton Mail as even the relatively limited free version enables automatic e2ee between Proton Mail users and a "password-protected emails" function to bring the same to non-Proton users.
