"User Level Security" over "User Created Security"

[rickyoswaldiow]

Good evening everyone. The database I am currently working on handles it's user accounts with a set of forms that only administrators of the db can access. It has groups and users but it simply stores the information on a table via some nifty modules that someone wrote. It does use the EncryptPass() function when calling the module but I was wondering just how secure this is? Is there any point in changing this to the User Level Security discussed here:
