End-to-End Encryption ensures that only the sender and receiver can read the messages, a hallmark of the Signal protocol.

Signal is renowned for its strong end-to-end encryption, safeguarding all messages, calls, and media files.

This makes unauthorized interception virtually impossible, a crucial feature for those prioritizing online security while using Signal.
