There's a new way to protect your Gmail from prying eyes. Experts say it's worth taking advantage of.

Google said it is adding end-to-end encryption (E2EE) to Gmail on the web, allowing registered Google Workspace users to send and receive encrypted emails within and outside their domain. End-to-end encryption is essential for any communications service because it allows only the sender and recipient(s) of messages to see the contents, Jeff Wilbur, the senior director of online trust at the nonprofit Internet Society, told Lifeire in an email interview.

“This means that the contents of the message can be seen by malicious actors or rogue employees and law enforcement can gain access under a warrant,” Wilbur added. “With end-to-end encrypted email, only the sender and recipient(s) have the key to decrypt the data, so it is safe from prying eyes of any kind.”

Client-side encryption (what Google calls E2EE) is already available for Google Drive, Google Docs, Sheets, Slides, Google Meet, and Google Calendar users. If you enable the new encryption now, Google says that data delivered as part of the email body and attachments will not be decrypted by Google servers. The email header, however, will not be encrypted.
