Your account in Plesk stores your access credentials and contact
information such as email, address, and phone number. Depending on how
you subscribed to a Plesk reseller plan, you can choose your username
and password yourself or receive them from your hosting provider. To
change your account password, click the Change Password link in the
navigation pane. Your username can only be changed by your provider. If
you forget your password and cannot log in to Plesk, click the Forgot
Your Password? link on the login page. Then enter your username and
the email specified in your contact information into the corresponding
fields. When you fill in this information, Plesk will send your password
to the specified email address.
If the contact details in your profile require updating, or you want to
add or remove some of them, click the Profile link in the navigation
pane or the link with your name at the top of the page and Plesk will
take you to a page where you can manage the details.
