Having sensitive information like Passport Number, Birth Date, etc. held in an app accessible with EOTI permissions is not a recommended solution. It's not often that I say this, but I might suggest an alternate solution for this particular use case.
One possibility would be to setup a Google Form that captures the needed info and sends the user an email with a link to edit the response later. You can capture the responses in Google Sheets and have that then connected to your Quick Base application using Zapier or Pipelines. While this is still not an ideal solution (anyone with the link can view/edit a response), it does provide a bit more security than an EOTI app.
