Change your two-step verification method and settings
After you set up your security verification methods for your work or school account, you can update the related details.
Using the Security info page
If your organization provided you with specific steps about how to turn on and manage your two-factor verification, you should follow those instructions first. Otherwise, you can get to your security verification method settings from the Security info page.
Note: If what you're seeing on your screen doesn't match what's being covered in this article, it means that your organization provides your own custom portal. For more information, contact your organization's Help desk.
To get to the Security info page
You can follow this link to open the Additional security verification page.
Or you can get to the Additional security verification page by following these steps:
-
Sign into the Microsoft 365 portal (office.com).
-
Select your avatar in the top right, then select View account.
-
Under Security info select Update info.
Note: For information about using the App passwords section of the Additional security verification page, see Manage app passwords for two-factor verification. App passwords should be used only for apps that don't support two-factor verification.
Turn on two-factor verification prompts on a trusted device
Depending on your organization's settings, you may see a check box that says "Don't ask again for n days" when you perform two-factor verification. If you've selected this option to stop two-factor verification prompts, and then you lose your device or your device is potentially compromised, you should have Microsoft 365 sign you out of all your devices to help protect your account. Unfortunately, you can't sign out of a specific device unless you have access to that device, so you need to sign out of all of them at once.
The next time you sign in you'll be prompted once again for your two-factor verification, as a safety measure.
Tip: Two-step verification is also known as multi-factor authentication. To learn more about it see What is: Multifactor Authentication.
