I want to use a Google Apps Script web app to download data from a specific Google Forms. In order to avoid having to login to get the data, I want to specify that the web app runs as me, and is accessible from anonymous users.
If I then keep the URL of that web app to myself (except for using it to get the data through the HTTPS request), is it reasonable to assume that nobody else can use it?
In other words, is there enough randomness in the script's URL to make it safe to use for accessing private data?
I want to use this script in a program, but I don't want to figure out how to login programmatically.
