Managing personal Outlook.com account settings, security, and privacy
That popup appears because Microsoft wants another way to verify identity and recover the account if access is lost. The supported way to stop it is to add another recovery or sign-in method.
For a personal Microsoft account:
- Sign in to the Advanced security options page.
- Select Add a new way to sign in or verify.
- Add a recovery method such as another email, phone, or a passkey.
- Make sure the recovery methods listed are current.
For a work or school account:
- When the prompt appears, select Next and follow the prompts to add another sign-in method.
- Or go to the Security info page and select Add sign-in method.
If the popup keeps appearing even though a phone number is already added, a community-provided workaround is to remove that phone number from Security info and add it again.
