Windows 10: Difference between Passwordless sign-in request and One-time Password?

What is the difference between Passwordless sign-in request and One-time Password?I have both on my Authenticator App for the same account. Interested to know what the difference is.

Passwordless Sign-in for MS account

On my desktop running Win10, 22H2, OS build 19045.2364 I'm the admin of the local account with no user accts. While I was reading one of Shawn's excellent tutorial's: Enable or Disable Passwordless Sign-in for Microsoft Accounts in Windows 10, I was hoping to find where to disable Passwordless Sign-in for MS accounts. I have it enabled because the sign-in screen into my Microsoft account lists "other sign-in options" (or something to those words). I also verified in the registry and netplwiz that its enabled. When selecting other sign-in options, a security key that I set up, first of all, disappeared all by itself recently. The security key is only one of two sign-in options for Passwordless sign-in that I ever set up. The other option was a Windows Hello PIN which I had up until this year but its no longer an option after I removed it myself. So where the problem comes in is after the authentication option using a security key is re-added, it ends up disappearing after about 24 hours later. When that happens, it leaves zero Passwordless Sign-in options to use (Windows Hello PIN was removed by myself in June). But Passwordless Sign-In will still remain enabled even though I can't sign-in Passwordless with any options. I'm left with signing in by using 2-step verification processes that I've had. Perhaps this is grasping at straws. I was thinking if there's a switch to disable Passwordless Sign-in to Microsoft Accounts that's turned off first, maybe then the security key can successfully be re-added permanently.

 

Google's passwordless future makes your phone an essential key

Passwordless sign-ins set to arrive in 'the coming year' Cybersecurity will see a major shift in online safety over the next year, as Google announced it is committed to bringing passwordless sign-ins across websites, apps and devices soon , and your phone will be the key. To push for a passwordless future, Google announced it will be expanding support for a common passwordless sign-in standard created by the FIDO Alliance and the World Wide Web Consortium. Apple and Microsoft will also be joining the transition from password-only authentication, as a way to protect against phishing attacks and malicious hacking methods.

Long boot time and passwords missing

The only reason I mention the account is that a Windows update recently was causing people to be signed into a temporary account, your password manager may be installed for all users but the list of passwords would be user specific, therefore the blank password list suggests a different account. *Smile
