What the desktop app actually is
Trezor Suite Desktop is a locally installed program for Windows, macOS and Linux. It contains the whole interface — dashboard, accounts, send and receive, settings — and it stores its own data (labels, accounts, preferences, display currency) in a local application directory on that machine.
Two consequences follow from that, and both are worth understanding before you choose it:
- Your funds are never in the app. Removing the application, or reinstalling the operating system, does not touch the coins. The wallet lives on the device and the blockchain.
- Your labels are in the app. Since portfolio labels are local data, they stay with that installation. If you move to a new computer, plan to relabel rather than expecting labels to arrive automatically.
What you need before installing
- A supported 64-bit desktop operating system — a current release of Windows, macOS or a mainstream Linux distribution. Very old releases may no longer be supported by the runtime the app is built on.
- A Trezor hardware wallet and the USB cable it shipped with. Cheap charge-only cables are a frequent cause of "device not found".
- Enough free disk space for the app plus its data, and an internet connection for blockchain data and firmware checks. The app keeps working offline in a limited way, but cannot broadcast anything.
Installing safely
The single most important step in the whole process is where the file comes from. Installers for wallet software are a favourite target for look-alike sites and poisoned downloads, and the file you run has full access to your machine.
- Start at the manufacturer's own website — reach it by typing the address yourself or from a bookmark you created earlier. Never from an advert, a search result marked "sponsored", an email or a link in a chat group.
- Check the address character by character before downloading. Imitation domains differ by a letter, a hyphen or a different ending.
- Prefer the signed release the manufacturer publishes for your operating system, and check the signature or checksum if you are comfortable doing so.
- Keep the file out of shared folders. Downloading on a machine other people use, or in a café, adds risk for no benefit.
Never install a wallet application from a link somebody sent you, no matter who appears to have sent it, and never install a "helper" tool a support message recommends. Software that does not come from the manufacturer's own site is a compromise waiting to happen.
First launch
On first start the app asks a few questions about how it should behave — display currency, whether to use Tor, and whether to send anonymous usage data. None of these decisions are permanent, and all of them can be revisited in Settings.
If the wallet is new, you create a wallet on the device and write down the recovery words as they appear on the device screen. If the wallet already holds funds, you connect it and the accounts load automatically — no recovery words are needed just to look at a balance. The full sequence is in the setup walkthrough.
App and firmware updates
Two different things get updated, and mixing them up causes confusion.
| Update | What it is | How it happens |
|---|---|---|
| Application update | New features, fixes and support for new assets | The desktop app notifies you and installs the new version |
| Firmware update | The software running inside the hardware wallet | You initiate it in the app; the device verifies the signature before installing |
| Recovery backup | Your wallet's recovery words — not an update at all | Created once, written down by you, never changed by an update |
Firmware updates require the device to be connected and unlocked, and usually need you to confirm two or three times on the device itself. Plan them for a moment when you have both the device and the backup to hand. If a firmware update ever interrupts halfway, do not panic-wipe: reconnect and let the app report the state of the device first.
Tor and network privacy
Blockchain queries reveal which addresses a viewer is interested in, and by default those requests carry an IP address. Turning Tor on routes the app's traffic through the Tor network so a blockchain server cannot easily associate your address with your internet connection.
Tor slows the app down — expect balances and transactions to load more slowly, sometimes noticeably — and the first connection after enabling it takes a little longer while circuits are built. For most people the trade-off is worth it; if you find it too slow, an alternative is to point the app at your own server instead.
Custom backend servers
A stronger privacy option is to stop using third-party blockchain servers at all. Suite can be configured to read data from your own Electrum-style server or from your own full node, so address queries never leave your control.
- You need hardware and bandwidth to run the node or server yourself.
- Setup is more technical than any other part of the app.
- In exchange you get the strongest privacy position available in the app, and independence from any third party's availability.
If that sounds like more than you need, Tor plus careful labelling already covers a lot of everyday privacy concerns. The security guide compares the options.
Troubleshooting the common problems
| Symptom | Likely cause | What to try |
|---|---|---|
| Device not detected | Cable, port or a locked device | Try the supplied cable, a different USB port, unlock the device with the PIN, and reconnect |
| Device asks for a PIN you never set | Untrusted or tampered device, or a factory firmware state | Stop. Check where the device came from before continuing |
| Balances never load | Network blocked, Tor still connecting, or backend unreachable | Turn Tor off to test, check the connection, then re-enable |
| App will not start after an update | Incomplete install or a conflicting security tool | Reinstall from the same official source; keep only one copy installed |
| Labels missing on a new computer | Labels are local data, not stored on the device | Relabel, or carry the app data over deliberately |
| Transaction stuck unconfirmed | Fee too low for current conditions | Use replace-by-fee where supported, or wait for the mempool to clear |
One rule covers all of the above: if a "solution" involves typing recovery words into software, a website or a support chat, it is not a solution. That step never exists in legitimate troubleshooting.
Desktop or web: which to choose
Choose the desktop app when the wallet is used regularly, when you want automatic updates and Tor without extra steps, or when the machine is your own. Choose the web version for occasional access on a machine you do not control, or immediately after reinstalling a system, when you simply need to check a balance.
Many people use both: desktop as the daily driver, web as a fallback when they are away from their own computer.
