Sign in and access
Use the account your hosting provider gave you to open your panel.
Open the secure address your hosting provider gave you and sign in with your panel account. If second-factor verification is enabled, complete that step before opening the panel.
Your account permissions decide which panel pages and actions you can use. Your hosting provider can explain which access is assigned to you.
If you cannot sign in, ask your hosting provider through its support ticket system. Do not send a password in a ticket.
