Hello,
Firstly, as you are using Wazuh OVA, you can change the password for your machines system user wazuh-user from default password wazuh to any custom one just by running the
passwd command in your OVA while logged in with wazuh-user and providing current and new password.
Secondly, to change the password for Wazuh indexer user (
admin), you can follow the documentation here:
https://documentation.wazuh.com/current/user-manual/securing-wazuh/wazuh-indexer.html
For changing the password, first you have to download the wazuh-passwords-tool.sh script:
Then, run the following command:
bash wazuh-passwords-tool.sh -u admin -p <mypassword>
Please replace <mypassword> with your expected password for the user admin.
This documentation
here also provides more information.
I hope this helps.
