When you try to view or edit sensitive info related to your Microsoft account – like your credit card details – we might ask you for a security code first to make sure that only you can get in to your account. But you can designate a PC as a trusted device. On trusted devices, you don't need to enter a security code each time you try to access sensitive info.
You can mark a device as trusted just by ticking a checkbox. When you're prompted to enter a security code to verify your identity, tick the I sign in frequently on this device. Don't ask me for a code. checkbox, and we won't ask you for a code in future.
If you don't currently have any trusted devices associated with your Microsoft account, here's how to mark the first one:
On the device you want to trust, sign in to your Microsoft account.
Under Password and security info, tap or click Edit security info.
This time, you'll be prompted to enter a security code.
Check your alternative email or your phone for a code sent by the Microsoft account team, and enter it in the text box.
Tick the I sign in frequently on this device. Don't ask me for a code. checkbox, then tap or click Submit.
You can now edit your info on this device whenever you want without entering another security code.
If you've already marked at least one device as trusted, the steps are a little different:
Choose how you want to receive your security code, then tap or click Next.
If you no longer have access to a device you've marked as trusted (for example, if your laptop is lost or stolen), we recommend that you remove all trusted devices from your Microsoft account at once, to help keep your account secure. (You can always trust devices again later.)
Sign in to your Microsoft account on another device.
If you're prompted for a security code, enter it and tap or click Submit.
Under Trusted devices, tap or click Remove all the trusted devices associated with my account.
Tap or click Remove all trusted devices.
Microsoft has made some changes to how you keep track of your trusted devices. For example, you no longer have to provide a unique name for each trusted device (or remember which is which!). You can also trust as many devices as you want – there's no longer a limit.
For these reasons, we've removed the list of trusted devices from the security info page. If you don't sign in to a particular trusted device at least once every two months, we'll automatically remove it from your Microsoft account. This helps keep your account secure in the event that a trusted device is lost or stolen without you realising it. You can always trust a device again later.
