# Pairing

“Pairing” is Gensparx’s explicit **owner approval** step.
It is used in two places:

1. **DM pairing** (who is allowed to talk to the bot)
2. **Node pairing** (which devices/nodes are allowed to join the gateway network)

Security context: [Security](/gateway/security)

## 1) DM pairing (inbound chat access)

When a channel is configured with DM policy `pairing`, unknown senders get a short code and their message is **not processed** until you approve.

Default DM policies are documented in: [Security](/gateway/security)

Pairing codes:

- 8 characters, uppercase, no ambiguous chars (`0O1I`).
- **Expire after 1 hour**. The bot only sends the pairing message when a new request is created (roughly once per hour per sender).
- Pending DM pairing requests are capped at **3 per channel** by default; additional requests are ignored until one expires or is approved.

### Approve a sender

```bash
gensparx pairing list telegram
gensparx pairing approve telegram <CODE>
```

Supported channels: `telegram`, `whatsapp`, `signal`, `imessage`, `discord`, `slack`, `feishu`.

### Where the state lives

Stored under `~/.gensparx/credentials/`:

- Pending requests: `<channel>-pairing.json`
- Approved allowlist store:
  - Default account: `<channel>-allowFrom.json`
  - Non-default account: `<channel>-<accountId>-allowFrom.json`

Account scoping behavior:

- Non-default accounts read/write only their scoped allowlist file.
- Default account uses the channel-scoped unscoped allowlist file.

Treat these as sensitive (they gate access to your assistant).

## 2) Node device pairing (iOS/Android/macOS/headless nodes)

Nodes connect to the Gateway as **devices** with `role: node`. The Gateway
creates a device pairing request that must be approved.

### Pair via Telegram (recommended for iOS)

If you use the `device-pair` plugin, you can do first-time device pairing entirely from Telegram:

1. In Telegram, message your bot: `/pair`
2. The bot replies with two messages: an instruction message and a separate **setup code** message (easy to copy/paste in Telegram).
3. On your phone, open the gensparx iOS app → Settings → Gateway.
4. Paste the setup code and connect.
5. Back in Telegram: `/pair approve`

The setup code is a base64-encoded JSON payload that contains:

- `url`: the Gateway WebSocket URL (`ws://...` or `wss://...`)
- `token`: a short-lived pairing token

Treat the setup code like a password while it is valid.

### Approve a node device

```bash
gensparx devices list
gensparx devices approve <requestId>
gensparx devices reject <requestId>
```

### Node pairing state storage

Stored under `~/.gensparx/devices/`:

- `pending.json` (short-lived; pending requests expire)
- `paired.json` (paired devices + tokens)

### Notes

- The legacy `node.pair.*` API (CLI: `gensparx nodes pending/approve`) is a
  separate gateway-owned pairing store. WS nodes still require device pairing.
