Change the Wazuh indexer passwords

In this section we will show you how to change the passwords of the Wazuh indexer users to secure your installation.

We provide a script to simplify the process of changing passwords, start by downloading it:

# curl -so wazuh-passwords-tool.sh https://packages.wazuh.com/4.3/wazuh-passwords-tool.sh

The script allows changing the password for either a single user or all the users present on the /usr/share/wazuh-indexer/plugins/opensearch-security/securityconfig/internal_users.yml file. It also offers the option to change the password of more than one user at once, getting them from a formatted file.

All the available options to run the script are:

Options	Purpose
-a / --change-all	Changes all the Wazuh indexer and Wazuh API user passwords and prints them on screen. To change API passwords -au\|--admin-user and -ap\|--admin-password are required.
-A, --api	Change the Wazuh API password given the current password. Requires -u\|--user, and -p\|--password, -au\|--admin-user and -ap\|--admin-password.

Change the password for single user

To change the password for a single user, run the script with the -u option. You may indicate the new password with the option -p. If no password is specified, the script will generate a random one.

# bash wazuh-passwords-tool.sh -u admin -p mypassword

This is the output of the script:

28/04/2022 10:17:50 INFO: Generating password hash
28/04/2022 10:17:55 WARNING: Passwords changed. Remember to update the password in the Wazuh dashboard and Filebeat nodes if necessary, and restart the services.

Change the passwords for all users

To generate and change passwords for all users, run the script with the -a option:

# bash wazuh-passwords-tool.sh -a

This is the output of the script:

28/04/2022 10:25:31 INFO: The password for user admin is EYzV0Q07poX53W395uChGVKYNEGMEkfe
28/04/2022 10:25:31 INFO: The password for user kibanaserver is PoXXlnylEcV3VKdJWqFzVAomHEmb1WO4

28/04/2022 10:25:31 WARNING: Passwords changed. Remember to update the password in the Wazuh dashboard and Filebeat nodes if necessary, and restart the services.

If the options -au and -ap are used, and the Wazuh manager is installed, the script will also change the passwords for the API users.

Change the passwords using a formatted file

To use a formatted file to indicate the passwords, run the script with the -f option followed by the file path. Use the following pattern to indicate the users and passwords in the formatted file:

For Wazuh indexer users, the file must have this format:

# Description
  indexer_username: <user>
  indexer_password: <password>

For Wazuh API users, the file must have this format:

# Description
  api_username: <user>
  api_password: <password>

If the -a option is used in combination with the -f option, all users not included in the file are given a random password.

The options -au and -ap are necessary to change the passwords for the API users.

In distributed deployments you will need to change the passwords in the nodes running the Wazuh dashboard and Filebeat, you can use wazuh-passwords-tool.sh to do this.
