Question details

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Renewing or purchasing a Microsoft 365 subscription and attempting to install and use it on a primary computer as well as a second computer.
- Observed behavior
- The user needs clarification on Microsoft 365 device limits and simultaneous sign-in rules to successfully set up Office on a second device.
Before proceeding, check your Microsoft account dashboard to determine whether you have a Microsoft 365 Personal/Family subscription or a Business/Work plan, as licensing rules vary between them.
Using Microsoft 365 Personal or Family on Multiple Devices
Microsoft 365 Personal and Family plans allow you to install the apps on multiple devices and stay signed in on up to five devices simultaneously.
If you have a personal subscription, you do not need to purchase a second license for your new computer. You can install Word, Excel, and PowerPoint on all your Windows, Mac, and mobile devices.
Open a web browser on your second computer, navigate to office.com, and sign in with the Microsoft account associated with your active Microsoft 365 subscription.
Click the 'Install apps' button in the upper-right corner of the dashboard to download the installer, then run the setup file to install the suite on your second computer.
Open any installed app, such as Word, and sign in. You can be signed into five devices at once. If you sign into a sixth device, Microsoft will automatically sign you out of one of the previous five.

Frequently Asked Questions
What happens if I sign into a sixth device with Microsoft 365 Personal?
If you exceed the five-device limit, Microsoft will automatically sign you out of one of your previously connected devices to make room for the new one. The software remains installed, but you will be prompted to sign back in if you want to use it on the disconnected device.
Do I need to buy a second subscription for my new laptop?
No. If you have an active Microsoft 365 Personal or Family subscription, your single plan covers multiple devices. You can simply log into your Microsoft account on the new laptop and download the software.
Can two people use the same Microsoft 365 Personal subscription on different computers?
While the software can be installed on multiple computers, a Personal subscription is meant for one user. Sharing your login credentials is not recommended. If you need to share Office with another person, consider upgrading to a Microsoft 365 Family plan, which supports up to six individual users.
Does WPS Office limit the number of devices I can use?
No, WPS Office can be downloaded and used on an unlimited number of devices for free. Your files can be synchronized across all of them using a single WPS account login.
