Off-the-record messaging, also known as OTR messaging, is a type of private conversation where the messages exchanged are encrypted, and neither party can be sure that the other is being truthful. Some synonyms for this type of messaging might include encrypted messaging, secure messaging, or confidential messaging. The point of off-the-record messaging is to have a private conversation that is shielded from prying eyes, and to ensure that important information is not leaked to unauthorized parties. If you are looking for a way to communicate sensitive information without worrying about security breaches or privacy concerns, OTR messaging might be the perfect solution for you.
