login notes vs secure notes

vellum

On a login page:
Are all the fields available to the login website?

ie, I can create a secret question & answer
and that's accessible to the login website.

Is the login notes section also available to the login website?
Or is that secure, like yellow secure notes?

I understand 1password is encrypted, when closed.
I'm asking if the login notes field wants to fill a website space, like the password field wants to fill a website space.

I'd like to move account numbers & details from the yellow secure notes to the login notes. But I don't want to do that if the notes field acts like other login fields.

Hope this is clear.
