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

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 operation. See Write Concern Specification.

Compatibility

This method is available in deployments hosted in the following environments:

Important

This command is not supported in MongoDB Atlas clusters. For information on Atlas support for all commands, see Unsupported Commands.

Required Access

To modify the password of another user on a database, you must have the changePassword 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:

Tip

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.

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

When prompted in mongosh for the password, enter the new password.

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

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