Why is my Microsoft Authenticator App not sending me the numbers when being prompted to.

Hello，Matteo Monaco

Thank you for posting in the Microsoft community.

I understand the issues you are having with the Microsoft Authenticator app, it can really cause anxiety.

Faced with this situation, I want to tell you that you are not alone, and we hope to do our best to help you link your school account just like you. The issue of not sending you a verification code when you authenticate in the Microsoft Authenticator app is usually related to the app's settings, device permissions, or account security settings.

1. Phone settings: Check that your new phone has the Microsoft Authenticator app installed correctly, and make sure the app has permission to send notifications.

2. Account Settings: Sometimes, the security settings of your account may need to be confirmed on your old device, especially if you change devices, and the authentication settings may need to be updated.

3. Network connection: Make sure your phone is connected to a stable Internet, whether it is Wi-Fi or mobile data. An unstable network may cause the verification code to fail to be sent.

All other methods simply pop up a new number to enter intonthe authenticator. All options are doing the same thing.

I understand that if you change the device you won’t receive a verification code but I think what I did was I deleted the app and when I redownloaded it my previous account with the verification code got lost and now it won’t send codes to me

My issue is a little different. When I log into my school account on my computer, I get a code; however, I do not get an authenticator notification to enter the code. My computer is sending the code but there is not notification from the authenticator to enter it.

What do I do?

either to check if apps is the latest updated or you can remove the account and reinstall auth apps

or last can try used others auth not Microsoft authenticator

1. Phone settings: Check that your new phone has the Microsoft Authenticate app installed correctly, and make sure the app has permission to send notifications.

2. Account Settings: Sometimes, the security settings of your account may need to be confirmed on your old device, especially if you change devices, and the authentication settings may need to be updated.

3. Network connection: Make sure your phone is connected to a stable Internet, whether it is Wi-Fi or mobile data. An unstable network may cause the verification code to fail to be sent.

1. Obviously the Authenticate APP is installed

2. What account settings? The phone, app or the account the OP is trying to log in to?

3. Standard troubleshoot answer that does not relate to the problem and is not helpful.

Is anyone having a problem with LinkedIn 2FA? Same issue, they send a code when you are logging in, but MS Authenticator app does not provide a code. If you don't have a code, you can't log in.

how to update authenicator setting

Apparently this is an ongoing problem with MS, and it shouldn't be ours. A customer should not have to do a search to fix problems and end up on a community board.

My issue is I cannot log into Edge, my Windows 11 PC, but yet I am logged on here as you can see. WTH?

Authenticator does not alert me with a code nor does sending code to my phone work. The error from MS "sorry try another day" or "method is not working right now" is not acceptable.

If you can open your Authenticator app there will be a temporary code available. Try using that.
