1 If you set your client to `always-on` (see the previous section for details), you can set a "device ID" for each device you use. Oragono will then remember the last time your device was present on the server, and each time you sign on, it will attempt to replay exactly those messages you missed.
2 You can set the SASL Username as `nick@phone` or `nick@laptop` while connecting. This allows you to fetch history based on your "DeviceID" which is `phone` or `laptop` in these cases.
3 If you only have one device, you can set your client to be always-on and furthermore `/NS SET autoreplay-missed true`. This will replay missed messages, with the caveat that you must be connecting with at most one client at a time.
4 You can autoreplay a fixed number of lines (e.g., 25) each time you join a channel using `/NS SET autoreplay-lines 25`.
5 You can manually request history using `/history #channel 1h` (the parameter is either a message count or a time duration). (Depending on your client, you may need to use `/QUOTE history` instead.)
6 You can also enable history for private messages called `DMs` by passing the following command: `/NS SET dm-history true`.
#### Sessions and Clients
- You can check how many of your sessions are online with `/NS SESSIONS `and the idle times for those.
- You can list your clients in further detail with `/NS CLIENTS list`
- You can use `/NS CLIENTS logout client-id/all` to either logout a single session or all sessions.
