Question details

The user is unable to use SMS verification during sign-in because the text message option has disappeared.

How to Fix the Missing 'Verify Identity by Text' Option

Product: Microsoft 365 / Microsoft Authenticator
Device & OS: not provided
Scenario: Attempting to sign in to a Microsoft account when prompted for multi-factor authentication (MFA).
Observed behavior: The 'Verify Identity by Text' option is entirely missing from the sign-in screen, leaving only an Authenticator app code prompt. Reinstalling or clearing the app does not restore the text option.

Before you start

Before proceeding with admin-level fixes, ensure that you have a stable network connection and try signing in using an InPrivate or Incognito browser window to rule out temporary cache issues.

Solution 1Recommended

Contact Your IT Administrator

For standard corporate or educational users, your organization's IT department dictates which authentication methods are permitted.

In many cases, an organization's IT administrator may have intentionally disabled text-message (SMS) authentication to enforce higher security standards, such as requiring only the Microsoft Authenticator app.

Locate IT contact information

Find the support email or phone number for your company's or school's IT helpdesk.

Request authentication reset

Ask the administrator to check if SMS verification is allowed for your account. If it is allowed, ask them to reset your Authenticator registration or manually add your phone number as an authentication method in the admin portal.

Note for Standard Users: You cannot bypass this restriction yourself. Reinstalling the Authenticator app will not restore the text option if it was disabled at the organizational level.

Solution 2

Contact Microsoft 365 Support (Global Admins Only)

Use this solution if you are the only Global Administrator for your organization and are completely locked out of your account.

Solution 3

Test Sign-in Using an Incognito or InPrivate Window

Browser cache and stored cookies can sometimes cause authentication prompts to load incorrectly or hide available options.

Frequently Asked Questions

Why did my organization disable the text verification option?

Many organizations actively disable SMS verification because it is considered less secure than app-based authenticators. SMS texts can be intercepted through SIM-swapping and phishing attacks, prompting IT admins to enforce Microsoft Authenticator instead.

Can I bypass the Microsoft Authenticator app if I lost my phone?

If your organization strictly enforces MFA, you usually cannot bypass it yourself once locked out. You must contact your IT administrator to clear your old MFA sessions and allow you to register a new device.

Will reinstalling the Authenticator app restore the text option?

No. Reinstalling or clearing the cache of the Authenticator app only resets the app itself. It will not restore the text option if SMS verification has been disabled at the tenant level by your administrator.
