# Validate Initiator

## Validate Initiator

{% hint style="danger" %}
Anyone can initiate a transaction pretending to be somebody with authority over an account. 
{% endhint %}

To validate whether the initiator of the transaction has authority over the account in the transaction, you can use `validateInitiatorOverBroadcaster` static function.

```typescript
const validAuth:boolean = await HiveMultisig.validateInitiatorOverBroadcaster(
                        initiator: string,
                        keyType: KeychainKeyTypes,
                        transaction: Transaction,
                      );
```
