PURPOSE: A user authentication method in driving an identical process for multiple users in a WLL system is provided to enable a user to log in to a screen process again using an identical user ID in case that the screen process ends abnormally and prevent screen process numbers from being duplicated. CONSTITUTION: In case that a user executes login after inputting a user ID and a password(S1), a system judges whether the same user ID was logged in(S3). If the same user ID was not logged in, the system deletes all the user IDs stored in a shared memory(S4). The system waits for a preset standby time so that another screen process in driving can rewrite its own user ID(S5,S6). If login is executed successfully, the system looks for empty areas of usable screen processes and determines screen process numbers in a preset sequence(S7). Then the system writes its own user ID in the nth field of the shared memory(S8). The system periodically monitors the nth field of the shared memory and judges whether another screen process deletes its own user ID. In case that its own user ID is deleted, the system rewrites its own user ID(S9).
