Migrating 2FA to a new device

Hi, I just changed phones and installed Google Authenticator on the new
phone, and migrated my Google code to the new authenticator.
 But my common-lisp.net code (and some other ones e.g. Cloudflare) are
still on the old phone.
 But the common-lisp.net one (on the old phone) doesn't seem to work
anymore.
 Is there a way to migrate this to a new phone without logging in (I doubt
it).

If not, can the admin temporarily disable my 2FA so I can get in and set it
up on the new phone?
