Your setup requires passwords.  An app-password is a valid password.  It never expires, thus not ideal.  When you are asked for the password, you either give it the never-expiring app-password, or your normal one.  In your case, when you give it the normal one, MFA kicks in.  (An App-Password replaces MFA and was a work-around for apps that did not work with MFA).  I suspect your old iPhone Mail app knows your App-Password, thus never asking for it.  

 

You can setup more verification methods (authenticator, etc).  Go to … https://MyApps.Microsoft.com,  click on your photo, go to profile, go to Additional Security Verification.

In order to use MFA with Skype For Business, We need to enable modern authentication for Skype for Business Online.

Steps to enable modern authentication for Skype for Business Online
https://aka.ms/SkypePowerShell

Check the current status of ClientAdalAuthOverride attribute.
Get-CsOAuthConfiguration | FL *ClientAdalAuthOverride*

Now run the following command to enable modern authentication for Skype for Business Online.
Set-CsOAuthConfiguration -ClientAdalAuthOverride Allowed

Verify that the change was successful by running the following:
Get-CsOAuthConfiguration


Post making the PowerShell changes it may take 15 minutes to couple of hours for the changes to take affect.
