Passwordless authentication not working

Question

Passwordless authentication not working

Alejandro Sastre Admin 21

I'm trying to activate passwordless login on my regular user account but I can't get it to work.
I have Authenticator, registered my domain, enabled phone authentication. in Azure selected Authenticator under authentication methods and added my user to test. Nothing happens when I login, I keep typing my password. I'm sure I must be missing something but not sure what.

Thank you
Alejandro

@Alejandro Sastre Admin Thank you for reaching out to us. As I understand you are setting passwordless authentication for one of your user's in the organization.

Refer to this article https://learn.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-passwordless-phone prerequisites for this feature are mentioned here.

As per the description you provided I believe you have configured the authentication policy for the user.

Do you have Enable phone sign-in option from the drop-down menu for the account registered within Microsoft Authenticator app ?

Does this feature working for any other users in your organization ? or is this a new setup ?

Let me know if you have any questions, please feel free to post back.

Yes I enabled the phone sign-in option on my iPhone.

Not yet, I'm testing with my user account first.

@Alejandro Sastre Admin Did a quick repro at my end with one of the test users in my tenant, passwordless authentication worked fine.

Apart from the steps which are mentioned in the above article, I tried the following step - After adding the account in the authenticator app, selected the account - choose the option to enable phone sign-in - which will register the device in Azure AD (will be seen in the user's profile something like below screenshot)

Once the device is registered, try to login portal.office.com and verify the experience, if the issue still persists, lets connect offline to discuss the same.

I came in this morning and I wasn't prompted for a password when login in to Onedrive, the Authenticator app option came up and worked.
The only question left is, should this also work for laptop login screen?

Thanks

@Alejandro Sastre Admin Yes, you can have the passwordless authentication deployed to the desktop users as well.

Planning/testing is needed for the same, refer to the below documentation which should help

Apparently it is possible to get stuck with a stale configuration. I just had a similar problem, and solved it with the following:

From the menu with the account "Disable passwordless sign in"
Then add it again to the account
