Microsoft MFA : Enabled or Enforced

Multi Factor Authentication (MFA)

Microsoft recommends using multi factor authentication for global tenant administrators. If you don’t do this, 60 days after the last reminder from Microsoft, the tenant is deactivated.

Warning: it’s not enough to activate 2-factor authentication … you also have to use it.

Enabled or Enforced

The problem is that activation is not enough. In fact, after activating the user, he must also log in with the MFA: at this point the user’s status changes from Enabled to Enforced.

You don’t have to have Global Admin with MFA in Enabled status but only in Enforced status.

Microsoft Azure Machine Learning testing csv import

For those of you who are experiencing with Microsoft Azure Machine Learning, a short note on importing csv files to build your own dataset. If you produce a csv using Microsoft Excel in a nation where thedecimal separator is “comma” (Italy in my case) , you will get a file that has “comma” (,) as decimal separator and “semicolon” (;) as field separator.

This format is not compatible with AML and should be brought to the American standards: “the dot” (.) As decimal separator and “comma” (,) as the field separator.

Open with notepad  your csv:

Transform your decimal separator: from comma to dot
Transform the separator of fields: from semicolon to comma
