Use a "backup" variable to authenticate the user with their profile. For example a user "logs in" - you can assign their ID number as a session variable (eg: 23) but ALSO assign a unique variable that you stored in the database when the account was created - eg CreateUUID().
Then when they login you can retrieve their information when the ID is 23 AND the UUID equals the value stored in the database, eg: 9FEF4148-B963-46D4-0A570610E956CBDE. You then merely need to check if the two session variable marry up to display, or not, the page.

The id feeds the page and extracts information and populates the form fields with the user's information. THE PROBLEM: If a user is viewing their customized information with their user id=23, than what would prevent them from view other people's information by editing the id value to say, id=24? SOLUTIONS: ??? 1) Should I scramble the value in some long string and extract a value from it? For example for id=23 replace it with id=ei38skdh23skdu83 and pull 23 out of the string? 2) Set a cookie that contains the same id value and if the values don't match kick them out to some other page? Any suggestions would be great.
