The **Access Token Lifespan** is a global setting that controls how long an issued access token stays valid before a user or service must re-authenticate. By default, access tokens expire after **90 minutes**. You must be an **Account Admin** to view or change global settings. ## Change the Access Token Lifespan 1. Click your profile in the top-right corner, then select **Admin Configuration**.

2. In Admin Configuration, select the **Global Settings** tab. 3. Scroll to the bottom of Global Settings to find the **Access Token Lifespan** field. Enter a value and choose a **Unit** from the dropdown. Available units are **Seconds**, **Minutes**, and **Hours**.

4. Click **Save** in the bottom-right of the page. The lifespan must fall within a valid range: **1 minute to 24 hours**. The field help text reads: "How long issued access tokens stay valid: 1 minute to 24 hours". Choosing a lifespan is a security tradeoff. Shorter lifespans are more secure but require users and service accounts to re-authenticate more often. Longer lifespans are more convenient but increase exposure if a token is compromised. ## Related * [Service Accounts](/getting-started/service-accounts) — machine identities that use access tokens * [Access Control](/cloud-red-essentials/access-control) — roles and permissions
