Your most sensitive emails in Gmail now have a much better privacy lock on your phone. Google has officially started rolling out end-to-end encryption for Gmail on Android and iOS devices.
For the first time, authorized users on Android and iOS devices can compose and read encrypted emails natively in the Gmail app without the hassle of downloading and installing third-party apps.
How does E2EE work in Gmail for mobile?
Gmail’s E2EE first launched for desktop users in April 2025, celebrating its 21st birthday. External receiver support was added later, in October 2025. However, smartphones did not receive this feature, leaving a significant privacy gap.
The April 2026 update finally closes this gap. If you have read about E2EE and how it works on other messaging platforms, you can already guess the mechanism in Gmail: only you and the recipient can see the email.
When composing an email, you can tap the lock icon, select the “additional encryption” toggle, and then send the email. If the recipient uses Gmail, the email will land in their inbox like any other regular email. However, if they are on another platform, they will receive a secure link to read and reply via a web browser (without a Gmail account).
Who actually has access to E2EE in Gmail for mobile?
Here’s the catch. Gmail for mobile gets E2EE, but only for Google Workspace Enterprise Plus accounts with the Assured Controls or Assured Controls Plus add-on. Administrators must first enable Android and iOS access via the client-side encryption interface.
In other words, personal Gmail users on mobile devices won’t get access. In any case, by closing the gap between Gmail for web and mobile, Google has eliminated a key pain point for customers evaluating Workspace compared to the Microsoft 365 suite.
