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:
The type of key prefixes are:
|The key is a Tailscale API access token.
|The key is a pre-authentication key.
|The key is a Tailscale OAuth client key.
|The key is a System for Cross-domain Identity Management (SCIM) key.
|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.
