# AccessKey
<a name="API_AccessKey"></a>

Contains information about an Amazon access key.

 This data type is used as a response element in the [CreateAccessKey](https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreateAccessKey.html) and [ListAccessKeys](https://docs.amazonaws.cn/IAM/latest/APIReference/API_ListAccessKeys.html) operations. 

**Note**  
The `SecretAccessKey` value is returned only in response to [CreateAccessKey](https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreateAccessKey.html). You can get a secret access key only when you first create an access key; you cannot recover the secret access key later. If you lose a secret access key, you must create a new access key.
