login using passwordless authentication, results in error "Check your Authenticator app" "That password is incorrect for your Microsoft account"

Question

Both me and a colleague on different devices with different accounts are experiencing the same error.

We try to log on to Microsoft Outlook (with personal accounts with passwordless enabled) we enter the email address and click next.

We get the number displayed on screen and select the same number on our Microsoft Authenticator push notification.

the goes through and the screen updated to a message showing:

"Check your Authenticator app

That password is incorrect for your Microsoft account"

We are both able to login with different method and use username and password.

Is Microsoft Authenticator broken some how ?

Answer 1

I believe the issue can resolved by creating a passkey on your device you're using to access this account.

I struggled with this now for over a week. I could get in if I used a password and then received a "push" approval from the Microsoft Authenticator. Once I did that in an "in Private" window I was offered the option to create a passkey for future logins. Since I did that I have not had an issue accessing my Outlook.com account.

Something broke somewhere in the past week or two.

Answer 2

I have the same issue. Now, I am unable to get codes sent via Outlook. That option has been removed from my account. I cannot add it back. To get codes getting pushed, I have to use Microsoft Authenticator App. Anyone else has this issue?

Answer 3

In my case this was being caused by my always on VPN on both my phone and computer. I didn't have to stop using the VPN, but I did have to set them both to the same region. As soon as I did that, the sign in through the authenticator app worked again. Not sure if it's relevant, but I also set them both to my home country for the sign in.

Answer 4

Please excuse my Google Translate English.
I don't know why, but when you try to log in with Firefox on both PC and mobile, the app works correctly by selecting the two identical digits. It hasn't worked on Chrome for days. I haven't tried other browsers, but for now, you can access your accounts with Firefox.

Answer 5

I have a solution that worked for me. by disabling autofill in Microsoft Authenticator, I exported all the passwords that were saved in the app to make sure I had a backup.

Then, I disabled autofill and stopped syncing. I was warned that all saved passwords in Microsoft Authenticator would be deleted, I confirmed the action. After that, the "Passwords" tab disappeared from the app. (Make Sure this Happened)

then tried signing in to my passwordless account again. I received the authentication code, selected it, and successfully logged into my account using Microsoft Edge. Since I faced the same issue before, I believe this method could be the solution.
