how to obtain 2 factor code for admin if email isnt going through OC 4.1.0.3

Thought email was setup correctly, so I turned on 2 factor for the admin page.

Well, guess email isnt correct, now it wont let me access any of the admin pages other than this one.

Isnt there an admin file somewhere that keeps this code in a file directory?

I tried the CONFIG.PHP pages in the root and admin folder?

Thank you
