Understanding the One-Person License Rules

Explains how the single-user license works for Office Home and Student 2021 in terms of activation, device limits, and shared computer usage.

The 'one-person' license means the Office Home and Student 2021 software is permanently bound to a single Microsoft account. Unlike Microsoft 365 Family, you cannot share access, cloud storage, or activation rights with other accounts.

1
Account binding

When you activate Office Home and Student 2021, the license is assigned to the exact Microsoft account used during the initial setup. This cannot be transferred to another user later.

2
Device installation limit

You are legally permitted to install and activate the included Office applications (Word, Excel, PowerPoint) on exactly one PC or Mac at any given time.

3
Shared computer usage

Other users can physically use the computer where Office is installed, but the license and any associated account benefits belong solely to the primary assigned Microsoft account. They cannot sign in with their own accounts to activate the software.

Understanding the One-Person License Rules
Sign-in requirement: You do not need to sign in every time you use the software offline. However, the initial activation and periodic license validation will require you to be signed in to the bound Microsoft account.
