The logout command terminates the current authenticated session:

{ logout: 1 }


If you're not logged in and using authentication, logout has no effect.

Because MongoDB allows users defined in one database to have privileges on another database, you must call logout while using the same database context that you authenticated to.

If you authenticated to a database such as users or $external, you must issue logout against this database in order to successfully log out.


Use the use <database-name> helper in the interactive mongo shell, or the following db.getSiblingDB() in the interactive shell or in mongo shell scripts to change the db object:

db = db.getSiblingDB('<database-name>')

When you have set the database context and db object, you can use the logout to log out of database as in the following operation:

db.runCommand( { logout: 1 } )
