The LM (LAN Manager) protocol was originally used in the 1980s. Developed by Microsoft and 3Com, the LM protocol was designed for authentication on local area networks, particularly in the context of early Microsoft operating systems. It played a critical role in network security during its time, helping to manage access to resources in varied networking environments.

The significance of the 1980s stems from this era being the foundation of several networking technologies and protocols that laid the groundwork for modern networking and security practices. In subsequent decades, the weaknesses of the LM protocol became apparent, leading to the development of more secure authentication methods.
