db.changeUserPassword()

Definition

db.changeUserPassword(username, password)

Updates a user’s password. Run the method in the database where the user is defined, i.e. the database you created the user.

Parameter Type Description
username string The name of the user whose password you wish to change.
password string

The user’s password. The value can be either:

  • the user’s password in cleartext string, or
  • passwordPrompt() to prompt for the user’s password.

Tip

Starting in version 4.2 of the mongo shell, you can use the passwordPrompt() method in conjunction with various user authentication/management methods/commands to prompt for the password instead of specifying the password directly in the method/command call. However, you can still specify the password directly as you would with earlier versions of the mongo shell.

writeConcern document Optional. The level of write concern for the creation operation. The writeConcern document takes the same fields as the getLastError command.

Required Access

To modify the password of another user on a database, you must have the changeAnyPassword action on that database.

Behavior

Warning

By default, db.changeUserPassword() sends all specified data to the MongoDB instance in cleartext, even if using passwordPrompt(). Use TLS transport encryption to protect communications between clients and the server, including the password sent by db.changeUserPassword(). For instructions on enabling TLS transport encryption, see Configure mongod and mongos for TLS/SSL.

MongoDB does not store the password in cleartext. The password is only vulnerable in transit between the client and the server, and only if TLS transport encryption is not enabled.

Example

The following operation changes the password of the user named accountUser in the products database to SOh3TbYhx8ypJPxmt1oOfL:

use products
db.changeUserPassword("accountUser", passwordPrompt())

When prompted in the mongo shell for the password, enter the new password.

You can also pass the new password directly to db.changeUserPassword():

use products
db.changeUserPassword("accountUser", "SOh3TbYhx8ypJPxmt1oOfL")
