Yesterday (i.e. January 3), the beta-testers of Windows 10 received a new version of this system. Insider Preview Build number 18309 introduces the option of logging in to our secure Microsoft account without entering a password. Instead, the user receives a text message with a one-time code, which is then entered in the login window. This procedure is repeated each time you try to access your account on a new device - later you can choose whether you want to protect your profile with a PIN code, face scan or fingerprint (using the Windows Hello function).
It is worth noting that if you want to use this option, you must also have an unprotected Microsoft account. To create such an account, go, for example, to the account creation page and click on "Use phone number instead", and after completing the whole procedure - add it to the list of users of that particular system (in the system settings).
Windows 10 users who do not take part in the tests (information on how to sign up can be found at this address) will be given access to the aforementioned options around April, when the system receives a new update. On the official Windows blog you will also find an extensive list of other fixes provided by the latest test version of the system.
We have known that Microsoft plans to completely abandon passwords in the future since last May, when the giant from Redmond shared with the users the idea of "a world without passwords" and since then has been testing the solutions proposed at that time. It is worth mentioning that the aption of logging into your Microsoft account using the method described above was introduced in April 2018, but so far it has been available only to beta-testers of Windows 10 Home.
