+
+Each credential has a `type` field (`default`, `external`, or `balancer`) and a required `tag` field.
+
+##### Default Credential
+
+```json
+{
+  "tag": "a",
+  "credential_path": "/path/to/.credentials.json",
+  "usages_path": "/path/to/usages.json",
+  "detour": "",
+  "reserve_5h": 20,
+  "reserve_weekly": 20,
+  "limit_5h": 0,
+  "limit_weekly": 0
+}
+```
+
+A single OAuth credential file. The `type` field can be omitted (defaults to `default`). The service can start before the file exists, and reloads file updates automatically.
+
+- `credential_path`: Path to the credentials file. Same defaults as top-level `credential_path`.
+- `usages_path`: Optional usage tracking file for this credential.
+- `detour`: Outbound tag for connecting to the Claude API with this credential.
+- `reserve_5h`: Reserve threshold (1-99) for 5-hour window. Credential pauses at (100-N)% utilization. Conflict with `limit_5h`.
+- `reserve_weekly`: Reserve threshold (1-99) for weekly window. Credential pauses at (100-N)% utilization. Conflict with `limit_weekly`.
+- `limit_5h`: Explicit utilization cap (0-100) for 5-hour window. `0` means unset. Credential pauses when utilization reaches this value. Conflict with `reserve_5h`.
+- `limit_weekly`: Explicit utilization cap (0-100) for weekly window. `0` means unset. Credential pauses when utilization reaches this value. Conflict with `reserve_weekly`.
+
+##### Balancer Credential

+{
+  "tag": "pool",
+  "type": "balancer",
+  "strategy": "",
+  "credentials": ["a", "b"]
+}
+```
+
+Assigns sessions to default credentials based on the selected strategy. Sessions are sticky until the assigned credential hits a rate limit.
+
+- `strategy`: Selection strategy. One of `least_used` `round_robin` `random` `fallback`. `least_used` will be used by default.
+- `credentials`: ==Required== List of default credential tags.
+
+##### Fallback Strategy
+
+```json

+  "tag": "backup",
+  "type": "balancer",
+  "strategy": "fallback",
+  "credentials": ["a", "b"]
+}
+```
+

+
+Proxies requests through a remote CCM instance instead of using a local OAuth credential.
+
+- `url`: URL of the remote CCM instance. Omit to create a receiver that only waits for inbound reverse connections.
+- `server`: Override server address for dialing, separate from URL hostname.
+- `server_port`: Override server port for dialing.
+- `token`: ==Required== Authentication token for the remote instance.
+- `reverse`: Enable connector mode. Requires `url`. A connector dials out to `/ccm/v1/reverse` on the remote instance and cannot serve local requests directly. When `url` is set without `reverse`, the credential proxies requests through the remote instance normally and prefers an established reverse connection when one is available.

+- `reverse`: Enable connector mode. Requires `url`. A connector dials out to `/ocm/v1/reverse` on the remote instance and cannot serve local requests directly.

+# Neighbor Resolution
+
+Match LAN devices by MAC address and hostname using
+[`source_mac_address`](/configuration/route/rule/#source_mac_address) and
+[`source_hostname`](/configuration/route/rule/#source_hostname) rule items.
+
+Neighbor resolution is automatically enabled when these rule items exist.
+Use [`route.find_neighbor`](/configuration/route/#find_neighbor) to force enable it for logging without rules.
+
+## Linux
+
+Works natively. No special setup required.
+
+Hostname resolution requires DHCP lease files,
+automatically detected from common DHCP servers (dnsmasq, odhcpd, ISC dhcpd, Kea).
+Custom paths can be set via [`route.dhcp_lease_files`](/configuration/route/#dhcp_lease_files).
+
+## Android
+
+!!! quote ""
+
+    Only supported in graphical clients.
+
+Requires Android 11 or above and ROOT.

+Must use [VPNHotspot](https://github.com/Mygod/VPNHotspot) to share the VPN connection.
+ROM built-in features like "Use VPN for connected devices" can share VPN
+but cannot provide MAC address or hostname information.
+
+Set **IP Masquerade Mode** to **None** in VPNHotspot settings.
+
+Only route/DNS rules are supported. TUN include/exclude routes are not supported.
+
+### Hostname Visibility
+
+Hostname is only visible in sing-box if it is visible in VPNHotspot.
+For Apple devices, change **Private Wi-Fi Address** from **Rotating** to **Fixed** in the Wi-Fi settings
+of the connected network. Non-Apple devices are always visible.
+
+## macOS
+
+Requires the standalone version (macOS system extension).
+The App Store version can share the VPN as a hotspot but does not support MAC address or hostname reading.
+
+See [VPN Hotspot](/manual/misc/vpn-hotspot/#macos) for Internet Sharing setup.
