Key prefixes
Tailscale uses prefixes as part of the ID for keys. The prefix starts with tskey- and is followed by the key type. For example, when you create a Tailscale API access token, the prefix is tskey-api, resulting in a key ID in the form of:
tskay-api-abcDEF1CNTRL-091234567890ABCDEF
The type of key prefixes are:
| Key prefix | Description |
|---|---|
tskey-api | The key is a Tailscale API access token. |
tskey-auth | The key is a pre-authentication key. |
tskey-client | The key is a Tailscale OAuth client key. |
tskey-scim | The key is a System for Cross-domain Identity Management (SCIM) key. |
tskey-webhook | The key is a webhook key. |
Note that all Tailscale-generated keys and secrets are case-sensitive. For more information about keys and secrets in general, see Key and secret management.
