Dear programmers:

I need to ask you a question, I hope you can guide me.

I have an application made on Asp.net that is online to answer a questionnaire.

There are two ways to access the questionnaire. One is through a control panel entering the passwords for "Client", "User", and "Password".

The other way is to do it directly through a link that immediately displays the questionnaire without having to enter the control panel keys.

Here is an example: Direct access to answer the questionnaire: http://evaluacionesdepersonal.com/Nom035/index.aspx?p=U0VORUZFWDIzMTI2OQ==

My doubts are: What is this type of shortcut league called?

How can they be created or where can I see how to create them?

How Can I do generate that codes to enter without login? Is there a converter or something like that?

Thank you very much in advance for any guidance you can provide me.

Cheers!
