 | `oid` | String, a GUID | The immutable identifier for the "principal" of the request - the user or service principal whose identity has been verified.  In ID tokens and app+user tokens, this is the object ID of the user.  In app-only tokens, this is the object ID of the calling service principal. It can also be used to perform authorization checks safely and as a key in database tables. This ID uniquely identifies the principal across applications - two different applications signing in the same user will receive the same value in the `oid` claim. Thus, `oid` can be used when making queries to Microsoft online services, such as the Microsoft Graph. The Microsoft Graph will return this ID as the `id` property for a given [user account](/graph/api/resources/user). Because the `oid` allows multiple apps to correlate principals, the `profile` scope is required in order to receive this claim for users. If a single user exists in multiple tenants, the user will contain a different object ID in each tenant - they are considered different accounts, even though the user logs into each account with the same credentials. |
 |`tid` | String, a GUID | Represents the tenant that the user is signing in to. For work and school accounts, the GUID is the immutable tenant ID of the organization that the user is signing in to. For sign-ins to the personal Microsoft account tenant (services like Xbox, Teams for Life, or Outlook), the value is `9188040d-6c67-4c5b-b112-36a304b66dad`. To receive this claim, your app must request the `profile` scope. |
 | `unique_name` | String | Only present in v1.0 tokens. Provides a human readable value that identifies the subject of the token. This value is not guaranteed to be unique within a tenant and should be used only for display purposes. |
-| `uti` | Opaque String | An internal claim used by Azure to revalidate tokens. Resources shouldn't use this claim. |
+| `uti` | String | Token identifier claim, equivalent to `jti` in the JWT specification. Unique, per-token identifier that is case-sensitive.|
 | `rh` | Opaque String | An internal claim used by Azure to revalidate tokens. Resources should not use this claim. |
 | `ver` | String, either `1.0` or `2.0` | Indicates the version of the access token. |
