Signature Field - Guest User - Auth Token

Actions & Logic

Hi,
I am currently working on a project where a page can be accessed by a guest user for the purpose of signing an agreement. I have just realised the signature field relies on there being an authenticated user for the storage of the signature against a unique file name / folder structure.

I am trying to do a custom structure so that all the signatures get saved into a folder signatures/ and are not linked to a userID. Has anyone been able to do this?

Lastly, in order to and some security I was hoping to pass a temp auth token to firebase from the correct URL to prevent unauthorised access, has anyone been able to do this?

What have you tried so far?

Changing firebase rules to allow guest users, writing a custom action etc.

Did you check FlutterFlow's Documentation for this topic?
