Hi, I see! that’s a really pain, isn’t it? so don’t worry, u can sort this out. So, it sounds like you’re stuck with the Microsoft Authenticator app, and you can’t access the code, yeah? If you’ve set up any backup options (like text or email), try using those to verify your identity. U should get a code sent to your backup method. If that doesn’t work, you might need to reset your Microsoft Authenticator appp. You can do this by going to the Security Info page on your Microsoft account by chrome or edge what ever, there you can manage your authentication methods. There, you should be able to remove and re-add the app. If none of that works, just only one way u can asks Microsoft Support, and they’ll walk you through unlocking the account. Keep your chin up, you'll get back in soon! Let me know how it goes.
