# トークン有効期間の制御 (クライアント単位)

  For **Authlete 2.x** documentation, see [2.x version](/ja/v2/configuration-reference/tokens-and-claims/token-duration-per-client).
</Info>

## Overview

In Authlete 3.0, token durations can be configured at multiple levels, including the **Service level** and the **Client level**. These durations can be set **statically** at these levels or configured **dynamically** based on specific scopes. For more details on dynamic configuration, refer to the [Token Duration Per Scope documentation](/configuration-reference/tokens-and-claims/token-duration-per-scope).

This short article explains how to set token durations for **access tokens**, **refresh tokens** and **ID tokens** at the **client level**.

***

## Configuring Token Duration for a Client

To configure the token duration for **access tokens** or **refresh tokens**, follow these steps:

### Access Token Duration

1. Log in to the [Authlete Management Console](https://console.authlete.com).
2. Navigate to **Client Settings > Tokens and Claims > Access Token**.
3. In the **General** section, locate the **Enter Duration** field.
4. Set the desired duration for access tokens in seconds (as shown in the screenshot below).
5. Click **Save Changes** to apply the configuration.

### Refresh Token Duration

1. Log in to the [Authlete Management Console](https://console.authlete.com).
2. Navigate to **Client Settings > Tokens and Claims > Refresh Token**.
3. In the **General** section, locate the **Enter Duration** field.
4. Set the desired duration for refresh tokens in seconds (as shown in the screenshot below).
5. Click **Save Changes** to apply the configuration.

### ID Token Duration

1. Log in to the [Authlete Management Console](https://console.authlete.com).
2. Navigate to **Client Settings > Tokens and Claims > ID Token**.
3. In the **ID Token Duration** section, locate the **Enter Duration** field.
4. Set the desired duration for ID tokens in seconds (as shown in the screenshot below).
5. Click **Save Changes** to apply the configuration.

## Example

Assume there is a service and two clients registered with it. The values of the access token duration are configured as follows:

| Entity   | Access Token Duration (seconds) |
| -------- | ------------------------------- |
| Service  | 86,400                          |
| Client 1 | (not set)                       |
| Client 2 | 3,000                           |

Under these conditions, Authlete’s [/auth/authorization/issue](/api-reference/authorization-endpoint/issue-authorization-response) API responds to implicit grant flow authorization requests from the clients as follows:

### Response to an authorization request from Client 1

```json theme={null}
{
    "type": "authorizationIssueResponse",
    "accessTokenDuration": 86400,
    "responseContent": "https://client.example.org/cb/example.com#access_token=1zT0XRynwLryWYRKCYSDjrwku5sD-WQTCtC1tnfExZE&token_type=Bearer&expires_in=86400&scope=openid"
}
```

**Explanation**: The access token duration for the Service is used since no value is configured for Client 1.

### Response to an authorization request from Client 2

```json theme={null}
{
   "type": "authorizationIssueResponse",
   "accessTokenDuration": 3000,
   "responseContent": "https://client.example.org/cb/example.com#access_token=xg79MJucCq8f8QPA2_o9_q5nfzgbRQycgVwYSvMSWTY&token_type=Bearer&expires_in=3000&scope=openid"
}
```

**Explanation**: The access token duration for Client 2 is used since it is explicitly set.
