A small “Encrypted” label with a lock icon is starting to appear in iMessage, and it is not a warning sign. For iPhone users, the marker is a visible reminder that the conversation is protected by end-to-end encryption.
The change matters because Apple is making a security layer that has long worked in the background easier to notice. In practical terms, only the sender and the recipient can read the messages exchanged through iMessage.
What the new label actually means
Apple uses the label to show that the conversation is fully encrypted. That means neither the carrier nor Apple can read the contents of an iMessage exchange.
The protection has been part of iMessage since the service launched with iOS 5 in October 2011. What is different now is not the security itself, but the way Apple surfaces it on screen.
Photos and videos are protected too
The encryption does not apply only to text messages. Photos and videos sent through iMessage are also covered by end-to-end encryption, or E2EE.
Even if traffic were intercepted by hackers, the content would still be difficult to read. Apple continues to position this security model as one of the core strengths of its devices and services.
Why the label is more visible now
The new display is becoming more noticeable after the latest iOS update introduced a clearer approach to transparency. In May, Apple released iOS 26.5 with RCS end-to-end encryption, while also making it more obvious to users that their conversations are encrypted.
RCS differs from iMessage because it can be used to message non-Apple devices. Its full encryption is not entirely new, but Apple is now highlighting that protection more openly.
Not every device will show it yet
Not all users will immediately see the “Encrypted” label. On devices still running older iOS versions, the updated display may not appear.
That does not mean the core security of iMessage has changed. The messages remain encrypted in the background; Apple has simply made the protection easier for users to see.
iMessage still offers more than security
Beyond encryption, iMessage also has a useful function when signal is limited. On devices running iOS 18 or later, it can send simple text and emoji via satellite without a cellular or WiFi connection.
That can be helpful in places with no network, such as during camping or trekking. With the “Encrypted” label now more visible, Apple is also reinforcing iMessage as a secure and flexible communication service.
