I wrote a script that needs to store the username and password of a specific user in order to be used by a trigger on a weekly basis. I am storing these credentials as script properties so all users within a project can run the app as long as User 1 adds their credentials

For example: My code is asking via ui to enter a username and password and stores the response as

  let properties = PropertiesService.getScriptProperties();

  let username = properties.getProperty('username');
  let password = properties.getProperty('password');

  let usernamePrompt = ui.prompt("User Credentials","Enter username", ui.ButtonSet.OK_CANCEL);
  username = usernamePrompt.getResponseText();

  let passPrompt = ui.prompt("User Credentials",'Enter Password',ui.ButtonSet.OK_CANCEL);
  password = passPrompt.getResponseText();

   properties.setProperty('username',username);
   properties.setProperty('password', password);

Question 1:
User 1 downloads the app and installs it enters their credentials. User 1, user 2, user 3 etc can use the app within User 1’s project without any issues because User 1 credentials are stored.

However, if User 2 downloads the same add on, will they be prompted to enter their own credentials or will User 1 credentials be saved to User 2’s project?

Question 2:
If User 1 downloads and installs the app into project 1, and adds their credentials into project 1, will these credentials be available if User 1 decides to use this app in project 2? Or will they be prompted to enter credentials again into project 2?
