# Authentication

> How authentication, single sign-on, and access controls work across the LOIS for Word web app and the Microsoft Word add-in to keep contract data secure.

LOIS for Word uses Microsoft 365 authentication, giving legal teams seamless and secure access across web and Word.

### Authentication system

LOIS for Word integrates directly with your Microsoft 365 environment, so you can:

* Log in using existing Microsoft credentials
* Access LOIS for Word directly inside Word without a separate login
* Benefit from Microsoft’s built-in security: SSO, MFA, conditional access, and more
* Avoid context switching—contract review stays in Word where lawyers work

No need for password management or account provisioning—LOIS for Word aligns with the tools your team already uses.

### Dual-layered access control

LOIS for Word offers two levels of control:

#### 1. In-app user access (LOIS for Word web)

In the [Users](https://app.pincites.com/users) tab on the LOIS for Word web app, admins can:

* Add or remove users
* Set organization-level permissions
* Control access to contracts and playbooks

#### 2. Microsoft Word access (admin-controlled)

From your Microsoft 365 Admin Center:

* Approve and deploy the LOIS for Word add-in via **Integrated Apps**
* Assign access to specific users or groups
* Manage deployment centrally with no individual installs needed
