What is Trezor Suite?
Trezor Suite is the official, comprehensive desktop and web application designed by Trezor to manage your hardware wallet and digital assets. It moves beyond simple transaction sending and receiving, offering portfolio tracking, exchange integration, and, most importantly, a clear, guided interface for all critical security tasks.
Its primary purpose is to act as a secure bridge between your offline, physical hardware device and the online cryptocurrency network. All private keys—the actual secrets that control your funds—**never leave the hardware wallet**. Trezor Suite merely prepares the transaction details for the device to sign securely.
The Immutable Safety Rule: Your Recovery Seed
The 12, 18, or 24 words of your **Recovery Seed** (sometimes called a backup phrase or mnemonic) are the single, most crucial piece of information for the safety of your funds. It is the master key to your entire wallet, including all assets managed through Trezor Suite.
CRITICAL WARNING: Physical Isolation
- **NEVER** digitize your Recovery Seed. Do not take photos, save it as a file, type it into a computer, or store it in any cloud service.
- **ALWAYS** write it down on the provided recovery card or engrave it in metal.
- **NEVER** tell anyone your Recovery Seed, including Trezor Support. They will never ask for it.
Trezor Suite Security Checklist
Follow these guidelines every time you use your hardware wallet with Trezor Suite to ensure maximum protection against threats.
Verify Source Integrity
Only download Trezor Suite from the official Trezor website or the official desktop application installer. Phishing sites can mimic the web interface to steal your credentials.
Confirm On-Device Screens
When sending a transaction, the final recipient address and amount must be manually verified on the physical screen of your Trezor device. **Never trust the computer screen alone**, as malware can swap address information.
Set a Strong PIN
Always set a PIN on your Trezor device. This protects your device if it is lost or stolen. The PIN is entered directly on the device, not the computer keyboard, to prevent keylogging attacks.
Use a Passphrase (Optional but Recommended)
A Passphrase (or "Hidden Wallet") adds a second layer of security on top of the Recovery Seed. If an attacker gains access to your seed, the passphrase prevents them from accessing your funds without this additional secret word.
Regular Firmware Updates
Use Trezor Suite to manage firmware updates. Only install official firmware, which Trezor Suite automatically verifies cryptographically to ensure its authenticity.
The security of your digital assets ultimately relies on your own diligence. By understanding and strictly following these practices, you leverage Trezor Suite and your hardware wallet's full potential for self-custody.
