You restore a Ledger after losing or resetting a device, or when moving your accounts to a new device.
Turn on the Ledger and choose the option to restore from an existing recovery phrase.
Enter your 24-word phrase on the device, in the correct order. The device will guide you word by word.
Choose a new PIN for the device. This PIN protects the restored wallet.
In Ledger Live, reinstall your coin apps and add your accounts back. Your funds will reappear because they live on the blockchain.
Never enter your recovery phrase into Ledger Live, a website, or any app. It is entered only on the hardware device itself.
