# Permissions

Handles all Security Token Permissions related functionality Permissions a Secondary Key has over the Identity. A null value means the key has all permissions of that type (i.e. if `tokens` is null, the key has permissions over all of the Identity's Security Tokens)

**`note`** this method is of type [ProcedureMethod](/polymesh-sdk-api-reference/docs-v10/interfaces/proceduremethod.md), which means you can call `createGroup.checkAuthorization` on it to see whether the Current Account has the required permissions to run it

**`note`** this method is of type [ProcedureMethod](/polymesh-sdk-api-reference/docs-v10/interfaces/proceduremethod.md), which means you can call `inviteAgent.checkAuthorization` on it to see whether the Current Account has the required permissions to run it

Revoke an Agent's permissions for this Security Token

**`note`** this method is of type [ProcedureMethod](/polymesh-sdk-api-reference/docs-v10/interfaces/proceduremethod.md), which means you can call `removeAgent.checkAuthorization` on it to see whether the Current Account has the required permissions to run it

**Parameters:**

| Name    | Type                                                                                                      |
