Your account on the main wpcd.cloud site has a separate password than each of your wpcd.cloud panels.
We do this as a security precaution – access to one should not automatically grant an attacker access to the other!
So it is possible that you might be trying to login to one or the other and mixing up the passwords.
A simple resolution is to just use the password reset form on either the main wpcd.cloud site or on your panel site (depending on which one you’re looking to use.)
Your 2FA (if enabled) will be different for each site as well!
