App Updates vs Firmware Updates — What's the Difference?

Ledger has two distinct update streams. They look similar in Ledger Live but work differently underneath.

Firmware update

Changes the operating software on the device itself. Requires device confirmation. Touches the secure element's OS layer.

App update

Updates a specific coin app (Bitcoin, Ethereum, etc). Can be uninstalled and reinstalled without affecting the recovery phrase. Runs inside Ledger's OS layer.

Impact on your funds

Neither update type can touch the phrase or PIN. Both require on-device confirmation. The practical difference: firmware updates are rarer and more impactful; app updates are routine.

Safety reminder: Use only the official Ledger site and Ledger Live. Never type your recovery phrase or PIN into a webpage and never share them with anyone. Pause and verify the moment anything looks unusual.
