title: API Tokens

<head>

</head>
By default, some cluster-level API tokens are generated with infinite time-to-live (`ttl=0`). In other words, API tokens with `ttl=0` never expire unless you invalidate them. Tokens are not invalidated by changing a password.
You can deactivate API tokens by deleting them or by deactivating the user account.
## Deleting Tokens
To delete a token:
1. Go to the list of all tokens in the Rancher API view at `https://<Rancher-Server-IP>/v3/tokens`.
1. Access the token you want to delete by its ID. For example, `https://<Rancher-Server-IP>/v3/tokens/kubectl-shell-user-vqkqt`
1. Click **Delete**.
The following is a complete list of tokens generated with `ttl=0`:
| Token | Description |
| ----------------- | -------------------------------------------------------------------------------------- |
| `kubeconfig-*` | Kubeconfig token |
| `kubectl-shell-*` | Access to `kubectl` shell in the browser |
| `agent-*` | Token for agent deployment |
| `compose-token-*` | Token for compose |
| `helm-token-*` | Token for Helm chart deployment |
| `*-pipeline*` | Pipeline token for project |
| `telemetry-*` | Telemetry token |
| `drain-node-*` | Token for drain (Rancher uses `kubectl` for drain because there is no native Kubernetes API) |
## Setting TTL on Kubeconfig Tokens
Admins can set a global time-to-live (TTL) on Kubeconfig tokens. Changing the default kubeconfig TTL can be done by navigating to global settings and setting [`kubeconfig-default-token-ttl-minutes`](#kubeconfig-default-token-ttl-minutes) to the desired duration in minutes. The default value of [`kubeconfig-default-token-ttl-minutes`](#kubeconfig-default-token-ttl-minutes) is `0`, which means that tokens never expire.
:::note
This setting is used by all kubeconfig tokens except those created by the CLI to [generate kubeconfig tokens](#disable-tokens-in-generated-kubeconfigs).
:::
## Disable Tokens in Generated Kubeconfigs
1. Set the `kubeconfig-generate-token` setting to `false`. This setting instructs Rancher to no longer automatically generate a token when a user clicks on download a kubeconfig file. When this setting is deactivated, a generated kubeconfig references the [Rancher CLI](../cli-with-rancher/kubectl-utility.md#authentication-with-kubectl-and-kubeconfig-tokens-with-ttl) to retrieve a short-lived token for the cluster. When this kubeconfig is used in a client, such as `kubectl`, the Rancher CLI needs to be installed to complete the log in request.
2. Set the `kubeconfig-token-ttl-minutes` setting to the desired duration in minutes. By default, `kubeconfig-token-ttl-minutes` is 960 (16 hours).
## Token Hashing
Users can enable token hashing, where tokens undergo a one-way hash using the SHA256 algorithm. This is a non-reversible process: once enabled, this feature cannot be disabled. It is advisable to take backups prior to enabling and/or evaluating in a test environment first.
To enable token hashing, refer to [this section](../../how-to-guides/advanced-user-guides/enable-experimental-features/enable-experimental-features.md).
This feature affects all tokens which include, but are not limited to, the following:
- Kubeconfig tokens
- Bearer tokens API keys/calls
- Tokens used by internal operations
## Token Settings
These global settings affect Rancher token behavior.
| Setting | Description |
| ------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| [`auth-user-session-ttl-minutes`](#auth-user-session-ttl-minutes) | TTL in minutes on a user auth session token. |
| [`kubeconfig-default-token-ttl-minutes`](#kubeconfig-default-token-ttl-minutes) | Default TTL applied to all kubeconfig tokens except those [generated by Rancher CLI](#disable-tokens-in-generated-kubeconfigs). **Introduced in version 2.6.6.** |
| [`kubeconfig-token-ttl-minutes`](#kubeconfig-token-ttl-minutes) | TTL used for tokens generated via the CLI. **Deprecated since version 2.6.6, and removed in 2.8.0.** Rancher v2.8 and later instead use `kubeconfig-default-token-ttl-minutes` for all kubeconfig tokens. |
| [`auth-token-max-ttl-minutes`](#auth-token-max-ttl-minutes) | Max TTL for all tokens except those controlled by [`auth-user-session-ttl-minutes`](#auth-user-session-ttl-minutes). |
| [`kubeconfig-generate-token`](#kubeconfig-generate-token) | If true, automatically generate tokens when a user downloads a kubeconfig. |
### auth-user-session-ttl-minutes
Time to live (TTL) duration in minutes, used to determine when a user auth session token expires. When expired, the user must log in and obtain a new token. This setting is not affected by [`auth-token-max-ttl-minutes`](#auth-token-max-ttl-minutes). Session tokens are created when a user logs into Rancher.
### kubeconfig-default-token-ttl-minutes
Time to live (TTL) duration in minutes, used to determine when a kubeconfig token expires. When the token is expired, the API rejects the token. This setting can't be larger than [`auth-token-max-ttl-minutes`](#auth-token-max-ttl-minutes). This setting applies to tokens generated in a requested kubeconfig file, except for tokens [generated by Rancher CLI](#disable-tokens-in-generated-kubeconfigs). The default value is `0`, which means that tokens never expire.
**Introduced in version 2.6.6**.
### kubeconfig-token-ttl-minutes
Time to live (TTL) duration in minutes, used to determine when a kubeconfig token that was generated by the CLI expires. Tokens are generated by the CLI when [`kubeconfig-generate-token`](#kubeconfig-generate-token) is false. When the token is expired, the API rejects the token. This setting can't be larger than [`auth-token-max-ttl-minutes`](#auth-token-max-ttl-minutes).
**Deprecated since Rancher v2.6.6.**
### auth-token-max-ttl-minutes
Maximum Time to Live (TTL) in minutes allowed for auth tokens. If a user attempts to create a token with a TTL greater than `auth-token-max-ttl-minutes`, Rancher sets the token TTL to the value of `auth-token-max-ttl-minutes`. Auth tokens are tokens created for authenticating API requests. The default value is `0`, which means that tokens never expire.
**Rancher v2.6.6 and later: Applies to all kubeconfig tokens and api tokens.**
### kubeconfig-generate-token
When true, kubeconfigs requested through the UI contain a valid token. When false, the kubeconfig contains a command that uses the Rancher CLI to prompt the user to log in. [The CLI then retrieves and caches a token for the user](../cli-with-rancher/kubectl-utility.md#authentication-with-kubectl-and-kubeconfig-tokens-with-ttl).
