Hello @Bitwardy444 and welcome to the community,
I utilize custom fields for multiple items, including as you mentioned certain “security questions” that are needed for sites, and other things related for a specific login entry I may have such as a related account’s API keys, etc.
Are you aware of the Hidden custom field type?
I believe this will suit your needs, as this allows for the same
custom field entry as you are used to with Text based custom fields, but allows these fields to be hidden by default, with the ability to unhide and view the contents, as well as the ability to copy all custom fields to clipboard as standard.
For some reason when I tested it earlier I thought it didn’t allow me to view and didnt have copy function. I will give it a test again and let you know how it goes.
Could you perhaps be trying to add hidden fields to an Organization item?
If so then that item or collection may be assigned the Hide Passwords access control which would prevent Hidden custom fields to not allow for easy View or Copy capabilities for users’ assigned with that access control.
