OAuth 2.0
OAuth 2.0 is the secure authorization protocol used by Microsoft, Google, and other providers to grant applications access to user data - without exposing passwords. It enables your intranet to request access to services like SharePoint, Microsoft Graph, or Teams using secure, time-limited tokens.
When a bank or credit union sets up Microsoft 365 or Azure AD integration, OAuth 2.0 governs how access tokens are issued, refreshed, and used behind the scenes.

Why It Matters
OAuth 2.0 is what makes secure intranet integrations possible. It ensures that only authorized apps can connect to sensitive data - while giving IT full control over scopes, permissions, and expiration.
Tokens issued through OAuth 2.0 allow your intranet to perform secure actions like reading calendars, searching SharePoint, or accessing a user's profile without requiring a login every time.
Microsoft and Azure Access Tokens
When you register your intranet as an app in Azure, OAuth 2.0 is used to issue an access token that authorizes API requests. These tokens are short-lived and include the scopes (permissions) granted during consent.
- Access Tokens: Used to access Microsoft Graph or SharePoint APIs
- Refresh Tokens: Used behind the scenes to silently renew access
How SimplifyIT Helps
We handle the OAuth 2.0 handshake, token management, and app registration so you don't have to. Whether you're connecting your intranet to SharePoint, Microsoft Entra ID, or Graph, we ensure it's done securely and efficiently.
