Google has extended Gmail’s end-to-end encryption for Workspace users to iOS and Android, allowing mobile users to write and read encrypted messages natively within the Gmail app for the first time.
This feature is part of Gmail’s client-side encryption (CSE) offering, which until now has been limited to the desktop. According to the Google Workspace update, users no longer need to download additional apps or use separate mail portals to manage encrypted emails on mobile, and the experience is now built directly into the existing Gmail app on both platforms.
Google says encrypted messages can be sent to any recipient regardless of their email provider. If the recipient uses Gmail, the message arrives as a standard email thread. If they use a different provider, they can read and respond through a secure interface without needing to install anything.
The feature is available now for both rapid release and scheduled release domains. Access requires an Enterprise Plus plan with the Assured Controls or Assured Controls Plus add-on, which is Google’s compliance-focused division aimed at business and public sector customers. Administrators must first enable the Android and iOS clients through the CSE administrator interface in the administrator console before users can access the feature.
To encrypt each message, users tap the lock icon inside the compose window and select “more encryption” before writing.
