Security researchers have documented multiple phishing sites using this exact accented spelling and page title to steal recovery phrases from users . The only legitimate setup portal is **trezor.io/start** (plain ASCII, no accent). *** ## The Official Setup Process Getting started with a Trezor hardware wallet takes roughly 15 minutes and follows a strict security-first sequence. The official flow is designed around one principle: your private keys never leave the device. ### Step 1: Download Trezor Suite from the Official Source Before connecting your device, download the official companion application, **Trezor Suite**, exclusively from `trezor.io/trezor-suite` or the Trezor GitHub repository . The desktop app is available for Windows, macOS, and Linux. A web version exists at `suite.trezor.io/web`, but the desktop application is recommended for enhanced security . Be aware that Windows may display a SmartScreen warning during installation. This is a known false positive related to Trezor's code-signing certificate. Verify that the publisher is listed as **Trezor Company s.r.o.** before proceeding . ### Step 2: Connect and Install Firmware Plug your Trezor into your computer using the provided USB cable. Trezor devices ship **without firmware pre-installed** for security reasons—this prevents tampered devices from being pre-loaded with malicious software . Trezor Suite will detect the device and guide you through installing the latest official firmware. You may choose between Standard firmware (supports all coins) or Bitcoin-only firmware for a minimized attack surface . ### Step 3: Create Your Wallet and Back Up the Seed Select "Create a new wallet" in Trezor Suite. Your device will generate a recovery seed—typically **12 or 20 words** depending on your model and manufacturing date, though older models use 24 words . These words appear one at a time on the device screen. Write them down **in exact order** on the recovery cards provided in the box. **Critical security rules for your backup:** * Never photograph, type, or store the seed digitally * Never enter the seed into any website or app—only directly on the Trezor device itself * Store the written backup offline in a secure physical location After writing the words, the device will ask you to confirm specific words to verify your backup is accurate . ### Step 4: Set a PIN Create a PIN of at least 4 digits (up to 50). This PIN is entered on the device itself and protects against physical access. After **16 incorrect attempts**, the device will wipe itself, protecting your funds from brute-force attacks . Avoid obvious sequences or personal dates. ### Step 5: Add Accounts and Begin Using Your Wallet Once setup is complete, Trezor Suite will prompt you to add cryptocurrency accounts. You can install coin-specific apps as needed and begin generating receive addresses. For every transaction, **verify the address and amount on the Trezor device screen**—this is the core security benefit of hardware wallets: the device displays what is actually being signed, preventing malware on your computer from altering transaction details . *** ## What Makes Trezor Different Trezor pioneered the hardware wallet category in 2013 and has maintained a **fully open-source** codebase ever since . This means security researchers worldwide can audit the firmware and software for vulnerabilities. The company is also entirely self-funded, with no venture capital pressure to prioritize growth over security . Trezor Suite integrates with over **70,000 dApps and DeFi protocols** via WalletConnect, supports thousands of cryptocurrencies across networks including Bitcoin, Ethereum, Solana, and Base, and is compatible with third-party wallets like MetaMask and Rabby for hardware-level security . *** ## Avoiding Phishing: The Real Threat The most dangerous moment in any hardware wallet user's journey is not device failure—it is **phishing**. Fake sites mimicking Trezor's setup page are specifically designed to trick you into typing your recovery seed into a web form. Legitimate Trezor software **never** asks for your seed phrase online . Only trust `trezor.io` and `suite.trezor.io`. Bookmark these addresses directly rather than searching for them. If you encounter a page that looks like Trezor but asks you to "verify" or "restore" your wallet by entering seed words, close it immediately—your funds are at risk. For official support, visit `trezor.io/support`. For firmware and Suite downloads, always start at `trezor.io/start`.
