+**BREAKING**: The deprecated identity and token manager services have been removed. This means that `coreServices.identity` and `coreServices.tokenManager` are gone, along with related types and utilities in other packages.

+**BREAKING**: The default backend instance no longer provides implementations for the identity and token manager services, which have been removed from `@backstage/backend-plugin-api`.
+
+If you rely on plugins that still require these services, you can add them to your own backend by re-creating the service reference and factory.
+
+The following can be used to implement the identity service:
+
+```ts
+import {
+  coreServices,
+  createServiceFactory,
+  createServiceRef,
+} from '@backstage/backend-plugin-api';
+import {
+  DefaultIdentityClient,
+  IdentityApi,
+} from '@backstage/plugin-auth-node';
+
+backend.add(
+  createServiceFactory({
+    service: createServiceRef<IdentityApi>({ id: 'core.identity' }),
+    deps: {
+      discovery: coreServices.discovery,
+    },
+    async factory({ discovery }) {
+      return DefaultIdentityClient.create({ discovery });
+    },
+  }),
+);
+```
+
+The following can be used to implement the token manager service:
+
+```ts
+import { ServerTokenManager, TokenManager } from '@backstage/backend-common';
+import { createBackend } from '@backstage/backend-defaults';
+import {
+  coreServices,
+  createServiceFactory,
+  createServiceRef,
+} from '@backstage/backend-plugin-api';
+
+backend.add(
+  createServiceFactory({
+    service: createServiceRef<TokenManager>({ id: 'core.tokenManager' }),
+    deps: {
+      config: coreServices.rootConfig,
+      logger: coreServices.rootLogger,
+    },
+    createRootContext({ config, logger }) {
+      return ServerTokenManager.fromConfig(config, {
+        logger,
+        allowDisabledTokenManager: true,
+      });
+    },
+    async factory(_deps, tokenManager) {
+      return tokenManager;
+    },
+  }),
+);
+```
