Encrypted Emails Are Now Available for Some Gmail Phone App Enterprise Customers
The rollout lets enterprise users on supported licenses read and compose encrypted mail on mobile while keeping keys under organization control.
Google has brought end-to-end encryption to Gmail on Android and iOS, allowing Enterprise Plus users to read and compose encrypted messages directly within the mobile app without extra software.
For over a year following the April 2025 web launch, Gmail's end-to-end encryption existed only on desktop browsers; this April 2026 update removes that constraint for mobile users.
Administrators must enable the feature in the Admin Console for Enterprise Plus users with Assured Controls; users tap the Lock icon and select "Additional encryption" to encrypt messages on their device.
The update strengthens Google's competitive position against Microsoft, which serves 80% of Fortune 500 companies; it addresses the mobile security gap that previously disadvantaged Google in regulated-sector procurement conversations.
Email remains the most exploitable channel in enterprise security, as Anthropic recently demonstrated; while this update aids regulated industries, individual consumers and small-business users remain without access to the feature.
