Windows 10: Authenticator not working

The user recently reset his password. After doing so, he was unable to log in with the authenticator app. When attempting to authenticate using OTP, he is prompted to enter a CAPTCHA. After entering the CAPTCHA, the following error appears. We also tried using the authenticator app, but when scanning the QR code, it shows another error. I have reset his password and re-registered MFA

Microsoft Authenticator

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you want to how the Microsoft Authenticator App works.

The Microsoft Authenticator app helps you sign-in to your accounts if you use two-factor verification. Two-factor verification helps you to access your accounts more securely, especially while viewing
sensitive information. Because passwords can be forgotten, stolen, or compromised, two-factor verification is an additional security step that helps protect your account by making it harder for other people to break in.

You can use the Microsoft Authenticator app in multiple ways, including:

• Respond to a prompt for authentication after you sign in with your username and password.
  
• Sign-in without entering a password, using your username, the authenticator app, and your mobile device with your fingerprint, face, or PIN.
  
• As a code generator for any other accounts that support authenticator apps.
  

I suggest you refer to the article for more information on
What is the Microsoft Authenticator app?and you may also
refer to the article about Microsoft Authenticator app FAQ

However, let me point you in the right direction where you can get the appropriate assistance regarding this issue. I suggest you to post your query in
Microsoft Authenticator App forums
where we have expertise and support professionals.

Hope it helps.

Regards,

Zaki
