Microsoft verification has stopped working on all my MacBooks. So I am locked out of my MacBook for. Verification

Based on the described behavior (verification code screen appears on Mac, code is sent and accepted on iPhone, but the Continue button on Mac does nothing or then reports “incorrect code”), the issue is most likely with how the Microsoft verification page is loading or how the session/cookies are handled on macOS, not with the GoDaddy mailbox itself.

Try these steps in order:

1. Test verification in a private browser session
   1. On the Mac, open Safari or another browser.
   2. Open a Private/Incognito window.
   3. Go to the Microsoft Security basics page and sign in: https://account.microsoft.com/security
   4. When prompted for verification, choose the same method (SMS/email code) and enter the code.
   5. If this works in a private browser, the problem is likely due to cached sign-in data or blocked cookies in the normal browser session or in the embedded sign-in window that Outlook/Office uses.
2. Clear cached sign-in state for Microsoft in the browser
   1. In the main (non‑private) browser, clear cookies/site data specifically for Microsoft/Outlook/Office domains.
   2. Close and reopen the browser and try the sign‑in again.
3. Reset the account sign‑in inside Outlook for Mac
   • In Outlook for Mac (Classic):
     1. Go to Outlook > Tools > Accounts.
     2. Select the GoDaddy/Microsoft 365 account.
     3. Use Reset Account (or remove and re‑add the account if Reset is not available).
   • In New Outlook for Mac:
     1. Go to Outlook Settings > Accounts.
     2. Remove the affected account.
     3. Quit Outlook, reopen it, and add the account again.
   When adding the account, a Microsoft sign‑in window will appear. Enter the password, then the verification code. If the embedded window still fails, choose the option to sign in via browser if offered, or add the account via the browser first (step 1) and then back in Outlook.
4. If verification codes are not accepted anywhere If the code is not accepted even in a private browser session:
   1. Go to the Security basics page: https://account.microsoft.com/security
   2. Select Update info.
   3. Choose a method that is working (for example, an alternate email) or select I don't have any of these to replace the security info.
   4. Complete the prompts to update or replace the verification method.
   If no verification method works at all, follow the guidance under I'm not getting my Microsoft account verification code and, if necessary, use the account recovery form referenced there.
5. If blocked or rate‑limited If many verification attempts have been made, the account can be temporarily blocked or rate‑limited:
   1. Stop trying repeatedly for at least 24 hours.
   2. After waiting, try again from a different network (for example, mobile hotspot instead of home Wi‑Fi) and from a private browser window.
   3. If a message such as Try another verification method appears, follow the guidance to switch to another method or network and avoid repeated attempts that can extend the block.
6. If nothing works and account is locked If verification and recovery keep failing and the account is locked, complete the Microsoft account recovery form as documented in the referenced articles, and wait for the lockout period to expire before trying again. Support and forum moderators cannot directly bypass these automated protections.

These steps address the common causes described in the Microsoft verification troubleshooting guidance: stuck or corrupted sign‑in sessions on a device, blocked or rate‑limited verification, and the need to update or replace security info when codes are not working.
