How to get to the Azure Additional security verification page?

if you already set the 2FA for Azure access (now its mandatory to have 2FA for admins), and you want to change the settings like you had "use App" and you want to change to text or call, or a scenario that you are using App and changed your phone, so you need to reconfigure again.

here is the link you go and set...

this option i did not get from Azure portal , earlier this was there.

hope this helps...
