But it also has the most to lose from any weakening in that security.Īpple’s iMessage update requires an adult in a family group to enable it for children in the same group. Its volume of fully encrypted messages likely outweighs the rest of the industry combined and, to its credit, it has publicly peddled the critical need to protect encryption. WhatsApp is my recommended go-to daily messenger, with the right blend of security and scale. But with this planned change, iMessage will be a platform I can no longer recommend. Its end-to-end encrypted architecture is the best in the business-seamless multi-device access, rolling backups, trusted device authentication but it stores copies of encryption keys in unencrypted iCloud backups and, worse, as soon as an iMessage user messages outside Apple’s walled garden, it reverts to SMS, a technology with pitiful, outdated security. IMessage is a strange hybrid when it comes to security.
