If you ever need to update your cPanel server root password, this be easily done via your WHM area.
Updating the root password:
Firstly, log into your server / WHM account. If you are unsure on how to do this, please view the following help article – ‘How to log into WHM‘
Once logged in, from your WHM home screen type in ‘change root password‘ within the search box, located in the top left of your WHM area, then click on ‘Change Root Password‘
On the Change Root Password page, you will then be prompted to enter the new password of your choice.
You can either enter a password of your choosing in to the ‘New Root Password‘ and ‘Confirm Password‘ boxes, which will then display how strong it is in the Strength box underneath. This will need to meet, or exceed the system requirement.
Alternatively you can click on the ‘Generate‘ button. This will then generate a random strong password in to the ‘New Root Password‘ if you are happy with this, then copy in to the ‘Confirm Password‘ box. You can also click on the ‘Down Arrow‘ to the right of the ‘Generate‘ button, which will provide you with options such as being able to select the generated password length, and whether to use only characters and numbers (no symbols), as well as all uppercase, or all lowercase characters.
Once you have your password entered, click on the ‘Change Password‘ button to proceed
The system will then update the root password for your server, and display a green message box to confirm that ‘The system successfully updated the root password’.
You can now test to make sure the new password is working by logging out of WHM, then logging back in.
