If you recieve a full or partial password, it means your password is not encrypted and visible to admins of the sites as well as any hackers who gain access to the site.
Ensure that the password is NOT used for any other account and especially your email. There are criminals out there who have "scanning lists". They know for example, that they will never break into a gmail account because Google's security is too good. Instead, they break into small shops and forums that don't invest in security at all. They get the email and password from the weak site, and try it against every other site on their scanning list like email, facebook, instagram, etc. To see if you reused the password.
If you have reused the password anywhere, change them all as soon as possible.
