Cant Login to Azure Portal

Common reasons you’re not getting the Microsoft Authenticator notification

1.Push notifications are disabled on the phone

Even if the app is installed, notifications may be blocked.

Check on your phone:

Settings → Notifications → Microsoft Authenticator

Allow:

Notifications

Banners

Sounds

Background refresh

Also disable Battery Optimization / Power Saving for the app.

2.Authenticator app is out of sync

Time drift can break MFA.

Fix:

Open Microsoft Authenticator

Go to Settings → Time correction for codes → Sync now

3.You’re signed into the wrong account in Authenticator

This happens a lot if you have multiple Microsoft or work accounts.

Check:

The account shown in Authenticator matches exactly the account you’re using to log into Azure

If missing → add it again

4.Network or VPN is blocking notifications

Corporate VPNs or restrictive networks can block push notifications.

Test:

Turn off VPN

Switch from Wi-Fi to mobile data

Try logging in again

5.Authenticator was partially reset or corrupted

Phone upgrades, restores, or app updates can silently break registration.

Symptoms:

App opens but no prompts arrive

Codes exist but Azure expects push approval

6.Your phone number / device is no longer registered

The device might have been removed from Entra ID security info.

If you’re an admin:

Entra admin center → Users → Your user → Authentication methods

Verify the device is listed

What you can do right now

Try alternate sign-in options

On the MFA screen:

Click “Sign in another way”

Use:

SMS

Voice call

Backup codes (if available)

If you are completely locked out

Option 1: Another Global Admin resets MFA (fastest)

If your tenant has another Global Admin:

Entra admin center

Users → Your account

Authentication methods → Require re-register MFA

Log in and re-enroll Authenticator
