How can I change my password in cPanel?
If you remember your old password, click Password & Security in the user menu to navigate to cPanel’s Password & Security interface (Home >> Preferences >> Password & Security).
If you forgot your password, your web hosting provider can reset it for you in WHM.
You can also reset your password via email if your web host enables the Email password reset setting in WHM’s Tweak Settings interface (Home >> Server Configuration >> Tweak Settings).
