In previous article I have enabled MFA for user alsajid@salonovi.cz and now I will test its behavior, while MFA Enabled and Enforced
User setup
When I log on for the first time with new user or try to access https://portal.onmicrosoft.com with user with just enabled MFA, Login window will look different and after typing my password it will require to set up MFA.
Office 365 talks to you in your prefered language, you can choose mobile application or mobile phone or normal phone to contact and pick up whether to be contacted by SMS or phone call.
I choose Mobile phone and SMS, next and I am required to verify my device
I have received SMS code
Verification went OK and in next step I am warned, that my password will be working only in browser (1) and for other aplications named in (2) I need to generate App Passwords (3) or agree, that these applications will not be used for my account (4)
APP Passwords (support for thick clients)
To generate App Passwords I was redirected to Windows Azure Active Directory logon screen, where I have been MFAuthenticated via SMS 🙂
Now I can create App Passwords
Next is name of application and then the password is generated and displayed once. You must copy it to clipboard
Now use the password as you have used your password for Office 365 previously. So basically you use your App Password instead of your Office 365 password.
Described here. This is most important link for support persons on MFA enabled customer´s helpdesk:

User´s output with MFA defined and registration process completed in Azure Active Directory (in my case default one way SMS)

Well so far so good but now , what I finally don´t like. Lets say, that App Passwords are need for not MFA ready apps..ok, you can define as much App Passwords as you want, you can name those, but you can use all of them to all aplications. That is a bit strange. I have generated two App Passwords and I was able to use both for LYNC client.
