How to list all users in the mongo shell?

Question

In the MongoDB shell, how do I list all users for the current database that I'm using?
I can't seem to find it anywhere on stackoverflow.

List belongs to DB users:

use db_name and db.getUsers() or show users

List according to the authentication type:

db.getUsers({ filter: { mechanisms: "SCRAM-SHA-256" } })

List with the credentials:

db.getUsers( {showCredentials: true, filter: { mechanisms: "SCRAM-SHA-256" }} )

If you like to list only user names and leave all other bulk info.. try

db.system.users.find({}, {"_id" : 1})

Following command can be used to get lis of user on a selected database.

By using find on a selected db

use admin;db.system.users.find({}, {"user": 1, "db": 1, "roles": 1});

To Get all the user on all the db

db.getUsers();or show users;

here you can get only user, db and roles nodes in response JSON.

Accepted Answer

You can do:

db.getUsers()

or

show users

The both commands print a list of users for the current database. See MongoDB documentation for User Management.
