Are these examples still current and expected to run?

I tried to implement the project shown above however it repeatedly loops, asking for a password.

Before I get too far into troubleshooting it I want make sure this code is has not been deprecated as there is another example found here that works but uses different code.

Is this code still the recommended approach for web apps?
