Question: 1 / 410

How can you identify which messages are encrypted in the Messages app on your iPhone?

Blue messages are encrypted, green messages are not

In the Messages app on an iPhone, the color of the message bubbles serves as an indicator of whether messages are encrypted or not. When you see blue messages, this indicates that the messages are being sent via Apple’s iMessage system, which uses end-to-end encryption, ensuring that only the sender and recipient can read the messages. Conversely, green messages signify that the messages are being sent over SMS, which is not encrypted and can potentially be intercepted during transmission.

This distinction is crucial for users who prioritize privacy and security in their communications. Understanding this color coding helps users identify at a glance whether their messages are secure or susceptible to interception. Other options do not accurately reflect the color coding system used by the Messages app or misrepresent the functionality of the app regarding encryption.
