Microsoft Security

What is a trusted device?

When you try to view or edit your credit card details or other sensitive information in your Microsoft account, you might need to enter a security code first, to make sure that only you can get in to your account. But you can designate a computer or other device as a trusted device. On trusted devices, you don’t need to enter a security code each time you try to access sensitive information.

How many trusted devices can I have?

You can trust as many devices as you want. There is no limit. If you don’t sign in to a particular trusted device at least once every two months, it’s automatically removed from your Microsoft account. This safeguard helps keep your account more secure in the event that a trusted device is lost or stolen without you realizing it. You can always trust a device again later.
