One has a fake "Forgot credentials" button that will invite people to go to their provider's app if they forgot their creds. The other doesn't have this option.

If you do not know how to use this great app which is Evil Portal, watch Talking Sasquach's tutorial: https://youtu.be/zfd7wADSkD4 In a nutshell, after installing Evil Portal on your Flipper (can be done easily through flipc.org):

1 Open QFlipper

2 Browse to SD Card > apps_data > evil_portal

3 There, you must upload the two files you find for each portal (index.html and ap.config.txt). YOU ONLY UPLOAD THE FILES FROM THE ONE PORTAL YOU WANT TO USE AT THAT POINT IN TIME! Unfortunately, you have to do this everytime you want to switch the portal you use.

4 Now, you can Start Portal in the Evil Portal app using a WiFi dev board (official or not, doesn't matter)

5 The portal you will see by connecting to yor access point will be the one for the provider you uploaded the files from!

If you want to change the Access Point's name, you can do it simply by editing the ap.config.txt file You can also tweak the indexes a bit if you know some HTML (there is some JS on the "ForgotCredentials" files)

Happy flippin'
