Does two-factor registration work when authorizing through an email client?

Question

Email

If, for example, two-factor registration is enabled on the same Yandex, then to enter it will be necessary to enter the code by scanning the QR code.
But if I want to authorize in my email client, for example, Microsoft office, how will two-factor authorization be processed there?? There is no interface for requesting a QR code.

Answer 1

Link transition.

Answer 2

At least it is confirmed that this mail exists, you can filter the "garbage" addresses.
You get a communication channel with the client.
