The phrasal verb "log off" is predominantly used in informal contexts, especially in the realms of everyday conversation about technology. It refers to the action of signing out or ending a session on a computer, website, or online service, thereby disconnecting the user from an electronic network. While it is highly common in discussions around personal computing, social media, and other internet-enabled activities, it is less frequently used in formal speech or writing. In formal texts, alternative expressions such as "sign out" or "terminate session" might be used to convey the same idea. "Log off" is often employed in command forms, like "Please log off your account for security," but can also be used descriptively, for example, "I need to log off by 5 PM." It gained prominence with the rise of computer usage and continues to be a staple in the lexicon of digital communication.
