From our Centova panel, we can modify the access password and also the external source password. To modify them, we enter our account in the Centova panel.
Then, we click on Settings > Configurations, in the left-hand sidebar

As soon as we enter, we have the options of Source Key and Administrator Key. The Source Key refers to the external source, and the Administrator Key refers to the Centova panel password.
In these two fields, we directly write the new passwords that we want them to have. We modify them and click on Update.

This way, we already have our keys changed.
