I have a valid login and password but the email address where the code is sent to no longer exists.

Hi -  I set up a Miro board using my work email many years ago.  I changed companies several years ago but kept using the same old work email and using password login for the Miro board, which was not a problem.   But now when I try to log in it prompts for a code which is sent to the old company’s email address.   The old company no longer exists.   I have a valid login and password but the email address where the code is sent to no longer exists.   Can anyone help?
