Multi-factor authenticcation with selector.
Hi, guys!
I have a task to develope multi-factor authorization for Linux systems with the ability to select an additional factor from the list.
PAM module is implemented. It can show chouce menu in terminal.
I have`t found a mechanism to display a dynamic dropdown menu or list for selecting an authorization factor. Found mentions of extensions for GDM but couldn't figure out how to use them.
If there is such a mechanism, tell me where to look for documentation on it. And if not, then I can suggest an idea for the implementation of a scripting language to display dynamic authorization scripts. Something similar to using JavaScript in the browser. I can also try to implement this idea.
