Captive Portal with login but no authentication

veldthui

Is it possible to set up Captive Portal to ask for a user name and log that name but not ask or require a password.
I want to know who is using my guest network but don't need the passwords so authentication is not needed.

That's very possible.
Start by creating a bunch of users, and give them all the same password, like '123'.

Now, use this :

to make your own 'html/php' captive portal login page :
I made one up for you :
Create a file, call it "portal.html" and upload it as a captive portal login page.

As you can see : you saw this already a million times in your live time. That is, you browser makes a page out of it. Now you've made the page yourself.
You probably have to adapt it a bit ^^

You saw that I used an image called "captiveportal-a-logo-that-I-uploaded.png".
This means you have to create an image, and all the file "a-logo-that-I-uploaded.png". It should be a png file of course. The suffix "captiveportal-" will get added automatically.

You can also remove the line where I use the image <p><img src ..... ></p>.

Use Services > Captive Portal > [CPZON] > File Manager to upload the image file.

edit : oops. Forgot one thing :
Copy the portal.html filo to error-page.html.

Add this line on a strategic place :

				<p style="color:red;"><b>$PORTAL_MESSAGE$.</b></p>

and upload this error-page.html file as the "Auth error page contents" page.

Thanks for that. It does however look like I need to know the names of the people before hand so as to create the users.
I have a Guest network that is limited bandwidth but anyone can use and I won't know who they are before hand. That was why I was asking if i could just get them to input their name and no password.

I think I can use your example for my other Wifi network that is not limited for my immediate neighbors who have asked if they can use it.

Why do you want them to enter a name ?
It's easy to create a text field, and have the content discarded.
Doing something with name the user entered, like writing it to a file, is another level.
It is technically possible that the portal login code adds the entered user name as a pfSense user, the ones you can see under "System > User Manager > Users" but this creates a situation where unknown / non trusted users starts to add 'stuff' to the pfSense config file ..... that's far from safe.

Like the password, you can also hard code a user name : all logged in users will actually use the same login name and password at that moment.

You don't want to use this method :

as the user now doesn't have to enter anything, right ?
