How do I sign in without Authenticator?

Question

I'm not able to log into my Outlook app on my Iphone cause It keeps automatically sending me into authenticator and since I'm in authenticator I can't verify the code whilst being in the app.

Answer 1

If you're unable to log into your Outlook app on your iPhone because it's redirecting you to the Authenticator app, you can try using an app password instead. App passwords are used for applications that do not support modern authentication. Here’s how you can proceed:

1. Set Up App Passwords: If your organization allows it, you can create an app password by going to your Microsoft account security settings.
2. Clear Sign-In Information: In the Outlook app, clear any saved sign-in information and restart the app.
3. Sign In with App Password: Use your username and the app password instead of your regular password to log in.

If your organization does not allow app passwords, you may need to contact your IT support for assistance with accessing your account without using the Authenticator app.

Answer 2

Hi @Andreana Ambros,

Welcome to Microsoft Q&A forum.

Thank you for posting your question in the Microsoft Q&A forum, and I’m sorry to hear you're having trouble accessing your account due to Microsoft Authenticator app.

To help determine the best solution for your situation, could you confirm the following details:

• Have you previously set up the Microsoft Authenticator app on any device for this account, or is this your first time trying to sign in? 
• Are you trying to sign in using a personal account (e.g., @hotmail.com) or a work or school account (@yourcompany.com or @ yourschool.com)?
• Have you recently changed phones or reset your Authenticator app?
• Is there any error message appearing while you attempt to sign in?
• Do you see the account listed in the Authenticator app, or is it asking you to add it again?

Once I have a clearer understanding of your current situation, I’ll be happy to assist you with greater accuracy. Please feel free to share any additional details you believe are relevant.

While we wait for your response, I'd like to provide some information that may help, in case your account is a work or school account:

When your school enforces multi-factor authentication (MFA) and only allows verification through the Microsoft Authenticator app, the system will not display other options such as SMS, email, or phone call unless those methods have been configured by your administrator. That’s likely why you're being prompted exclusively for the Authenticator app. 

We strongly recommend using Authenticator because it provides multi-factor authentication (MFA), adding a vital layer of security beyond passwords to protect accounts from phishing, credential theft, and unauthorized access. If you still wish to sign in Outlook without using Authenticator, please contact your IT admin, as only IT can provide alternative MFA options or make temporary adjustments in line with your school policy.

If you haven’t installed the app yet, you can follow this official guide to get started: How to add your accounts to Microsoft Authenticator - Microsoft Support  

You can also refer to this article for instructions on signing in using the app:  Sign in using Microsoft Authenticator - Microsoft Support 

If you need further assistance, you can reach out to your IT administrator and share the steps outlined in the article Manage user authentication methods for Microsoft Entra multifactor authentication. This will help them assist you in resetting your MFA settings and restoring access to your account. Once this is done, you’ll be prompted to set up MFA again on your new device during your next sign-in.

Note: Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

If you have any updates, feel free to leave a comment under this post. I’ll be happy to assist further. 

Thank you for your cooperation and understanding in resolving this matter.

I'm looking forward to your reply.

Hi Lia!

Hope you see this. Thank you for your quick reply. I had posted comments under your post, but they didn't seem to go through. Therefore I'll post an answer and also put a comment under your post again. I have previously set up Authenticator, but since I did change phones I seem to have problems now. Before I didn't have any problems. I am trying to sign in using a school account. I have an error message showing once i switch back to the outlook app (after it redirects me to Authenticator for sign in). I do see my account listed in Authenticator (just says needs password).
