## Core Concepts
**Microsoft Authentication Library (MSAL)** handles authentication with Microsoft Entra ID (formerly Azure Active Directory). It manages:
- Token acquisition and caching
- Silent token renewal
- Redirect/popup authentication flows
- Multi-tenant and B2B scenarios
### Package Versions
```json
{
"@azure/msal-browser": "^5.0.0",
"@azure/msal-react": "^3.0.0"
}
```
---
## Configuration
### Basic MSAL Configuration
```typescript
import { Configuration, PublicClientApplication, LogLevel } from '@azure/msal-browser';
export const msalConfig: Configuration = {
auth: {
clientId: import.meta.env.VITE_ENTRA_CLIENT_ID,
authority: 'https://login.microsoftonline.com/common', // Multi-tenant
redirectUri: window.location.origin,
postLogoutRedirectUri: window.location.origin,
navigateToLoginRequestUrl: true,
},
cache: {
cacheLocation: 'localStorage', // Persist across tabs

How to install
mdr add fabioc-aloha/alex_skill_mall/msal-authentication@git:20260728.80a7ab6mdr add fabioc-aloha/alex_skill_mall/msal-authentication@sha256:dcdc34358ad6cc22Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
