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.
To delete a token,
Go to the list of all tokens in the Rancher API view at
Access the token you want to delete by its ID. For example,
Here is the complete list of tokens that are generated with
|Access to |
|Token for agent deployment|
|Token for compose|
|Token for Helm chart deployment|
|Token for drain (we use |
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 to the desired duration in minutes. The default value of
kubeconfig-default-token-ttl-minutes is 0, which means tokens never expire.
This setting is used by all kubeconfig tokens except those created by the CLI to generate kubeconfig tokens.
Disable Tokens in Generated Kubeconfigs
false. This setting instructs Rancher to no longer automatically generate a token when a user clicks on download a kubeconfig file. Once this setting is deactivated, a generated kubeconfig will reference the Rancher CLI 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.
kubeconfig-token-ttl-minutessetting to the desired duration in minutes. By default,
kubeconfig-token-ttl-minutesis 960 (16 hours).
Users can enable token hashing, where tokens will 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.
This feature will affect all tokens which include, but are not limited to, the following:
- Kubeconfig tokens
- Bearer tokens API keys/calls
- Tokens used by internal operations
These global settings affect Rancher token behavior.

Time to live (TTL) duration in minutes used to determine when a user auth session token expires. When expired, the user will be required to log in and obtain a new token. This setting is not affected by
auth-token-max-ttl-minutes. Session tokens are created when a user logs into Rancher.
Time to live (TTL) duration in minutes used to determine when a kubeconfig token expires. When the token is expired, the API will reject the token. This setting can not be larger than
auth-token-max-ttl-minutes. This setting applies to a token generated in a requested kubeconfig file. Except those generated by Rancher CLI.
Introduced in version 2.6.6.
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 is false. When the token is expired, the API will reject the token. This setting can not be larger than
Deprecated since version 2.6.6, and will be removed in 2.8.0: This setting will be replaced with the value of
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 will set the token TTL to the value of
auth-token-max-ttl-minutes. Auth tokens are tokens created for authenticating API requests.
Changed in version 2.6.6: Applies to all kubeconfig tokens and api tokens.
When true, kubeconfigs requested through the UI will contain a valid token. When false, the kubeconfig will contain a command that uses the Rancher CLI to prompt the user to log in. The CLI then will retrieve and cache a token for the user.
