Gmail end-to-end encryption now available on mobile devices
We’re expanding Gmail end-to-end encryption (E2EE) to Android and iOS devices for Gmail client-side encryption (CSE) users. With Gmail E2EE, your users can confidentially engage with your organization's most sensitive data from anywhere on their mobile devices while ensuring data remains compliant and with your organizations sovereignty and compliance requirements.
For the first time, users can compose and read these E2EE messages natively within the Gmail app on Android and iOS. No need to download extra apps or use mail portals. Users with a Gmail E2EE license can send an encrypted message to any recipient, regardless of what email address the recipient has.
- Gmail recipients: If the recipient uses the Gmail app, the encrypted message will be delivered as a typical email thread to their inbox.
- Guest recipients: If the recipient doesn’t have the Gmail app, they can seamlessly and securely read and reply in their own native browser, ensuring that all users have a simple and secure interface, regardless of their email service or device.
This launch combines the highest level of privacy and data encryption with a user-friendly experience for all users, enabling simple encrypted email for all customers from small businesses to enterprises and public sector.
