Your FTP details can be easily found by opening Hosting → Manage:
And scrolling down to the FTP Accounts section:
There you will be able to see your FTP details: FTP IP and hostname, FTP username, FTP port.
You can also see the main FTP details on the Hosting → Manage → Details page (but you won't be able to manage your FTP password from there).
FTP password
FTP password is not displayed in the control panel due to security reasons. An FTP password is created for each domain either via onboarding, when you’re initially setting up the plan, or when you add an addon domain.
If you are not sure what password was set, you can change it through the Change FTP password button.
NOTES:
One FTP account is always created by default once you finish setting up your hosting
