You have to change the password and username. If you are still using the default combo your security is less.
Wilson is currently using the md5 hashing alogrithm for password hashing, Which is not secure, Upgrade your PHP to support blowfish alogrithm.
The salt for password hashing is randomly generated. If you want to change it you have to do it manually from the database.
