Does Ledger Need to Be Online All the Time? Does It Affect Security?
Overview: Does Ledger need to be online at all times, and does that affect its security?
Key takeaway: Signing happens offline on the device itself. The computer only goes online to broadcast and sync, so you don't need a constant connection — security hinges on official channels and device verification.
Points / steps:
- Always verify the address and amount on the device screen before signing — signing doesn't depend on network security.
- Only open Ledger Live on a trusted network; once sync is done you can disconnect for offline signing and delayed broadcast.
- If the network is unstable, sign offline, export the signed transaction, and broadcast it from a safer device.
- Update firmware and apps regularly, but never while connected to public Wi-Fi.
- If you see a suspicious prompt or anything asking for your recovery phrase, disconnect immediately and stop.
Safety reminder: The network is only for broadcast and sync — the private key never leaves the device. Do not update firmware or enter sensitive info on public or untrusted networks.
