After installation comes the part that actually matters: connecting the hardware wallet and understanding what each half of the system is allowed to do. Most confusion about hardware wallets — and most of the confidence tricks that target their owners — come from not knowing where the boundary sits.
Software and hardware: the division of labour
| Layer | What it does | What it cannot do |
|---|---|---|
| The desktop application (Ledger Wallet) | Displays balances and history, prepares transactions, talks to the device, installs device applications, fetches market data from online services | Sign a transaction by itself, reveal your recovery phrase, spend funds without a physical confirmation |
| The hardware wallet (the device) | Stores the keys, displays the transaction details on its own screen, signs only what you physically approve, holds the PIN | Show your portfolio without software, browse the internet, run on its own |
| The blockchain | Records transfers permanently and publicly | Reverse a confirmed transaction, recover a key, restore a lost recovery phrase |
The practical consequence is simple. The desktop application is a convenience layer: it can be uninstalled, reinstalled, replaced or moved to another computer without any effect on your assets. The device is the security layer: it never lets a key leave its secure element, and it never signs something you have not confirmed on its screen.
Where this guide shows an example of a transaction or a device prompt, the details are fictional and clearly generic. We never reproduce a real recovery phrase, a real address, a real PIN, or the interface of a third-party product. Anyone who asks you to type real recovery words anywhere — including into this website — is attacking you.
First launch, step by step
Start the application from your operating system, not from the installer
On Windows, use the Start menu. On macOS, launch it from the Applications folder after ejecting the disk image. Launching from a mounted installer or a temporary folder is a common source of permission errors and of "the application forgot my settings" reports.
Read the first-run screen rather than clicking through it
The first launch prepares a local data directory. Depending on the release, the setup flow may mention an optional paid recovery-subscription service; if you do not subscribe to it, choose the ordinary setup path offered on the same screen and dismiss the subscription panel. The desktop application does not require an email-and-password account: it stores its data locally on your computer.
Decide about optional diagnostics
Some releases ask whether to share anonymous usage diagnostics. This is a preference, not a requirement, and it has no effect on the security of your keys. Choose according to your own comfort and continue.
Connect a compatible hardware wallet
Connect the device with its supplied cable, directly to a port on the computer where possible. Unlock it with your PIN and leave it on its home screen. The application will look for the device automatically; if it does not, the troubleshooting library covers device detection in detail.
Confirm the connection on the device itself
A hardware wallet asks for permission before it talks to software. Approve that request on the device — never through a prompt that appears only on the computer screen. This is the first place where an impersonation attempt usually reveals itself: legitimate communication always gets confirmed on the hardware.
Install the applications your device needs
Open the application's device area to see which blockchain applications are installed on the device and how much storage remains. Install only what you use. Each device model has limited capacity, and an oversized installation simply fails with a storage message.
Add accounts for the assets you hold
Adding an account derives a public address from the device; the private key never moves. Verify the displayed address against the device screen the first time you use it — a habit worth keeping for every new address, because it defeats address-swapping malware.
Check the device status and firmware state
Look at the device information shown in the application: model, firmware version and, where supported, device health. If a firmware update is offered, read it on the device before approving, and only ever start it from the application itself.
Finish by checking for application updates
Use the application's own update mechanism, or a fresh download from the developer's official source. Do this after any firmware update, since the two are usually updated together.
Connecting a compatible hardware wallet
The desktop application communicates with compatible Ledger hardware wallets over USB. The connection process is deliberately physical, and each step exists for a reason.
Use the right cable. The cable supplied with the device is the one the manufacturer tested. Charge-only cables are a frequent and confusing cause of "device not detected".
Prefer a direct port. Unpowered hubs, docking stations, monitor USB ports and front-panel extensions all add failure points. If detection fails, moving the cable to a port on the computer itself is the fastest test.
Unlock the device before expecting recognition. A locked device will not appear to the application. Enter the PIN on the device.
Verify on the device screen, always. The device shows what it is being asked to sign. That screen — not the computer screen — is the authoritative record. A transaction that appears one way in the application and another way on the device is a red flag; cancel it and investigate.
Do not look for ways around device security. There is no legitimate reason to bypass a device confirmation prompt, to disable a security setting on the device, or to use a tool that claims to sign without confirmation. Any guide offering that is offering to remove the only protection you have.
A genuine installation and setup flow does not ask for your Secret Recovery Phrase, does not ask for your PIN in a web form, and does not ask you to send funds to an address to "verify" or "activate" anything. If a page, a pop-up, an installer screen or a chat window asks for any of those, you are talking to an attacker, whatever the branding says.
Installing applications on the device
Blockchain applications are installed onto the hardware wallet from inside the desktop application, not downloaded from websites. A few practical notes:
- Device storage is limited. The device area shows free space; install the applications you use and remove the ones you do not.
- The application must match the network. Installing the wrong application for a network simply produces an account that does not appear where you expect it.
- Never install device applications from a third-party site. A file claiming to be a device application, offered outside the official application, is either useless or malicious.
Adding accounts, and verifying addresses
An account is a view of a derived public address, not a container of coins. When you add an account, the application asks the device to derive an address and then displays it. Verify the first few characters and the last few characters on the device screen. This five-second habit defeats the most common class of malware that silently substitutes a destination address during a transfer.
Keeping software and firmware in step
| Component | How it updates | What to avoid |
|---|---|---|
| Desktop application | Through its own update mechanism, or a fresh verified download from the official source | Update links in emails, advertisements, chat messages or search ads |
| Device firmware | Through the desktop application, with confirmation on the device screen | Any firmware file offered by a third-party site |
| Device applications | Through the desktop application's device area | Sideloading files from forums or file-sharing sites |
A setup checklist you can actually finish
First launch and connection
Before signing anything, read the recipient address and the amount on the device screen. The computer screen can be lied to by malware; the device screen cannot. Ten seconds of reading is the cheapest insurance in this entire subject area.
