# Create access keys
> Create access keys for Object Storage using Cloud Console or API calls
This page shows you how to create the access keys you use to authenticate against CoreWeave AI Object Storage. You need access keys to call the [Object Storage S3 endpoint](/products/storage/object-storage/reference/object-storage-s3) and the [Object Storage API](/products/storage/object-storage/reference/object-storage-api-ref).
Access keys created using Cloud Console tokens can be permanent or temporary. Permanent keys don't expire, while temporary keys are valid for a specified duration. You can create access keys in the CoreWeave Cloud Console or with the CoreWeave API. Choose the Cloud Console method for an interactive workflow, or the API method when you need to automate key creation.
Production workloads should use [Workload Identity Federation](/products/storage/object-storage/auth-access/workload-identity-federation/saml-workload-federation) instead of Cloud Console tokens. Workload Identity Federation provides a more secure, controlled way to generate time-limited access keys using SAML assertions.
## Create access keys in the Cloud Console
Use this method to create a key interactively from the web UI. Key creation is restricted to administrators, so you must be signed in as a user with the **Object Storage Admin** IAM role (or equivalent legacy access, such as membership in the `admin` group).
1. In the Cloud Console, navigate to the [Access Keys](https://console.coreweave.com/object-storage/access-keys) page.
2. Click the **Create Key** button at the top right corner of the page.
3. In the dialog:
* For a temporary key, enter the desired duration in seconds and click **Create**.
* For a permanent key, select **Enable Permanent Key** and click **Create**.
## Create access keys with the API
Use this method to create keys programmatically, for example, from a script or automated workflow. To create access keys with the API, you must first create a JSON object that defines the key's properties. The JSON object must include the `durationSeconds` property, which specifies how long the key is valid.
The following sections show how to create permanent and temporary keys.
### Permanent keys
Permanent keys don't expire and can be used indefinitely. To create a permanent access key, set `durationSeconds` to `0` in a JSON object. The value of `0` in the example `data.json` indicates that the key doesn't expire.
```json title="data.json" theme={"system"}
{
"durationSeconds": 0
}
```
Then, submit the request to the `/access-key` endpoint with the JSON object in the body. Replace `[API-ACCESS-TOKEN]` with your API access token.
```bash title="Example request" theme={"system"}
curl -X POST https://api.coreweave.com/v1/cwobject/access-key \
-H "Content-Type: application/json" \
-H "Authorization: Bearer [API-ACCESS-TOKEN]" \
-d @data.json
```
A successful response returns the key with the `expiry` field set to `1970-01-01T00:00:00Z`, which indicates that the key doesn't expire.
```json title="Response status code 200" theme={"system"}
{
"accessKeyID": "CWABCDEFGHIJKLMN",
"expiry": "1970-01-01T00:00:00Z",
"principalName": "coreweave/my-user@test.com",
"secretKey": "cwo1234567890abcdefghijklmnopqrstuvwxyz1234"
}
```
### Temporary keys
To create temporary access keys, set `durationSeconds` to the desired duration in seconds. Temporary keys expire after the specified duration.
To begin, create a JSON object that defines `durationSeconds`. The following example creates a key with a 300-second (5-minute) duration.
```json title="data.json" theme={"system"}
{
"durationSeconds": 300
}
```
Submit the request to the `/access-key` endpoint with the JSON object in the body. Replace `[API-ACCESS-TOKEN]` with your API access token.
```bash title="Example request" theme={"system"}
curl -X POST https://api.coreweave.com/v1/cwobject/access-key \
-H "Content-Type: application/json" \
-H "Authorization: Bearer [API-ACCESS-TOKEN]" \
-d @data.json
```
A successful response returns the key. The `expiry` field is set to the time the key expires.
```json title="Response status code 200" theme={"system"}
{
"accessKeyID": "CWABCDEFGHIJKLMN",
"expiry": "2024-01-01T09:15:01Z",
"principalName": "coreweave/my-user@test.com",
"secretKey": "cwo1234567890abcdefghijklmnopqrstuvwxyz1234"
}
```
