How to change backup email used during password request?

Hello!  I'm new to Zoho and  briefly forgot my password, but when I did my password request, it sent it to my old work email--where I no longer work! I managed to remember my password, but the next time I forget (and I'm a password forgetter, sigh), I want to make sure the request is sent to my other active email. Where can I go to change this? I looked in Password and Security but can't seem to find it. Thanks for any help! :)
