how to login in to my microsoft authenticator app to change subscription

Hello @Leivi Saltman

From your description, the main issue isn't changing the Microsoft 365 payment method itself. You're being blocked by two-step verification/Microsoft Authenticator when signing in to the Microsoft account that owns the subscription.

One important point: you don't normally “log in to Microsoft Authenticator” to approve the request. When you sign in to your Microsoft account, Microsoft sends an approval notification to the Authenticator app on the phone where that account was previously configured.

First, open Microsoft Authenticator directly on your phone rather than waiting for the notification. Check whether the affected Microsoft account is still listed there.

If it is, retry the Microsoft account sign-in. You may be shown a number in the browser that needs to be entered or matched in Authenticator. Microsoft uses number matching for Authenticator approval requests.

If no notification arrives, check that:

• Notifications are enabled for Microsoft Authenticator.
• The phone has an Internet connection.
• Authenticator is updated to the latest version.
• Battery optimization/background restrictions aren't preventing Authenticator from receiving notifications.
• The account shown in Authenticator is the same Microsoft account you're using for the Microsoft 365 subscription.

You can also choose “Other ways to sign in”, “Use a different verification option”, or similar wording on the verification screen. If you previously registered another method, such as SMS, another email address, passkey, or security key, Microsoft may allow you to use it instead.

If you no longer have access to Authenticator

This is where you need to be careful.

If you've changed phones, deleted Authenticator, removed the account from the app, or otherwise lost access to the device that originally contained the authentication registration, don't repeatedly approve/reject or guess codes.

For a personal Microsoft account, start with Microsoft's Sign-in Helper:

aka.ms/sign-in-helper

Microsoft recommends the Sign-in Helper for determining the appropriate recovery path when you can't sign in.

If Microsoft offers account recovery, follow that process. However, Microsoft also makes an important distinction for accounts with two-step verification enabled: if two-step verification is turned on and you've lost access to all alternate verification methods, Microsoft Support can't simply bypass or reset the security protections for you.

So if you still have your old phone or another registered verification method, don't erase/remove it yet.

Once you regain access

After you can sign in to the Microsoft account that owns Microsoft 365, you can manage the subscription and payment information through your Microsoft account.

Microsoft also documents how to change the payment method associated with a Microsoft subscription.

I would first determine whether the affected account still appears inside Microsoft Authenticator. If it does, tell us what happens when you open Authenticator manually during the sign-in attempt.

If it doesn't, let us know whether you changed phones/reinstalled Authenticator and whether the verification page offers “Use a different verification method.” That will determine the appropriate recovery path.

And please don't post your email address, verification codes, recovery codes, QR codes, or payment information publicly here.
