How to change login email and notification address?

Hi NRFrs and my  fellow NRF aficionados,

I changed jobs and as a result I will lose access to my old work email address that I've used to log in all these years. Is there a straightforward way to change the login username which appears to be the same as my old work email address, or is the only effective way to do it to create a new account with the desired new email address and submit a merge request?

As always, thanks in advance for your help.
