User Login History (Register Time and Sign-in logs)
Register Time
You can specify that you want Business Central to register the amount of time that each user works with a company in the database. To register user time, use the General Ledger Setup and User Setup page in the client.
General Ledger Setup:

Register Time
Specifies whether to register user's time usage defined as time spent from when a user logs in and when the user logs out. Unexpected interruptions, such as idle session, timeout, terminal server idle session timeout, or client crash are not recorded.
User Setup
Register Time
Specifies whether to register the user’s time usage defined as the time spent from when the user logs in to when the user logs out. Unexpected interruptions, such as idle session timeout, terminal server idle session timeout, or a client crash are not recorded.

This is inserted when the user logs out.
To see the time use that has been registered, search for the User Time Registers page.
The biggest disadvantage of this method is that you can only see how long the user has been logged in on which day, and you cannot see the exact time of logging into the system.
