+# Models
+
+Some models behave differently and allow for access to different API fields when created via blueprint.
+
+### `authentik_core.token`
+
+:::info
+Requires authentik 2023.4
+:::
+
+Via the standard API, a token's key cannot be changed, it can only be rotated. This is to ensure a high entropy in it's key, and to prevent insecure data from being used. However, when provisioning tokens via a blueprint, it may be required to set a token to an existing value.
+
+With blueprints, the field `key` can be set, to set the token's key to any value.
+
+For example:
+
+```yaml
+# [...]
+- model: authentik_core.token
+  state: present
+  identifiers:
+      identifier: my-token
+  attrs:
+      key: this-should-be-a-long-value
+      user: !KeyOf my-user
+      intent: api
+```
