Continuous loop on Authenticator App

Question

I recently purchased the Microsoft 365 Business suite and registering on my computer it is prompting me to verify the code from the authenticator app on my mobile. On my mobile authenticator app it has me sign in and then asks for the validation code from the authenticator app, which I'm on so no code comes. With past businesses there were other options to get the code, like text. However, here I have no option but to cancel or verify. I've attempted Microsoft support 4X but the AI disconnects me half way through every time. Any suggestions?

Answer 1

What you're describing is a fairly common Microsoft authentication loop:

• On your computer, Microsoft asks for a code from the Authenticator app.
• On your phone, when you open the Authenticator app, it requires you to sign in.
• During sign-in, it asks for a code from the Authenticator app that you can't access because you're trying to get into it.

In that situation, the issue is usually that the Authenticator app was never fully set up on the phone, was reset, or is no longer connected to the account.

A few things to try:

1. Check whether Microsoft is expecting a number match, not a code

Recent Microsoft sign-ins often don't use a 6-digit code. Instead:

• The computer shows a 2-digit number.
• The Authenticator app sends a notification.
• You enter the number shown on the computer into the app.

If you're not receiving a notification, look for a "Approve sign-in request" or "Notifications" section in the Authenticator app.

2. Look for "Use another verification method"

On the verification screen in your browser, look carefully for options such as:

• "I can't use my Microsoft Authenticator app right now"
• "Use a different verification method"
• "Sign in another way"

Sometimes this link is small or hidden under More options.

3. Determine whether this is a personal or business account

Microsoft handles recovery differently depending on whether this is:

• A personal Microsoft account (Outlook, Hotmail, etc.)
• A Microsoft 365 Business account managed through a company tenant

If this is a business subscription that you purchased yourself, you may be both the user and the administrator. That can complicate recovery if the only MFA method configured was Authenticator.

4. Try signing into the Microsoft account security page

From another browser/device, attempt to sign in at:

Microsoft Account Security

If Microsoft offers another verification method there (email, phone, backup method), you may be able to regain access and then re-register Authenticator.

5. If this is a Microsoft 365 Business tenant you own

Try accessing the Microsoft 365 admin portal:

Microsoft 365 Admin Center

If you have another administrator account, that admin can reset MFA for your account. If you are the only global administrator and the Authenticator method is lost, Microsoft support usually has to perform an identity verification and MFA reset process.

6. Reinstalling Authenticator usually won't fix this

Unless you previously enabled cloud backup and can restore it, uninstalling/reinstalling the app often removes the existing registration and can make recovery harder.

A couple of questions

1. Is this a personal Microsoft account or a Microsoft 365 Business account?
2. Is this a brand-new Microsoft 365 Business subscription you just purchased, or an existing account you've used before?
3. Did you ever successfully set up the Microsoft Authenticator app on this phone before, or is this the first time it's asking?

Those details will help narrow down whether you're dealing with a setup issue, an MFA recovery issue, or an administrator-lockout scenario.
