Authentication

Tokens

There are 3 tokens

ID token

Contains basic information about user

  • Bound to one specific resource and user

  • Can include MFA claims

  • Can NOT be revoked before it expires (Unless CAE is in use for certain apps)

Access Token

Grant access to resource. Expiry range from 70 minutes to more then 24h.

Refresh Token

Can be used to request new access and id tokens. Expires in 90 days for inactive tokens and no expiry for active tokens.

  • One specific user

  • Can be revoked (when user resets their password, or manually revokes all active sessions)

Az PowerShell Module

Microsoft Graph

Install-Module Microsoft.Graph
