Understand the advanced security technologies that protect your digital assets and learn how to maximize your protection.

Core Security Technologies

Secure Element Chip

Military-grade secure element (CC EAL5+) stores your private keys in tamper-resistant hardware that's physically isolated from your computer.

✓ Certified to highest security standards

PIN Protection

Your device is protected by a PIN that you enter directly on the Trézor. After multiple failed attempts, the device wipes itself.

✓ Brute force protection included

Recovery Seed Backup

Your 12 or 24-word recovery seed is generated offline and never transmitted. It's your ultimate backup for wallet recovery.

✓ BIP39 standard compliance

Transaction Verification

Every transaction must be physically confirmed on your device screen. What you see is what you sign - no hidden changes possible.

✓ Protection against malware

Open Source Firmware

All firmware code is publicly auditable. The security community continuously reviews and improves the codebase.

✓ Transparent and verifiable

Air-Gapped Security

Your private keys never touch the internet. All cryptographic operations happen offline within the secure hardware.

✓ Complete network isolation

Protection Against Common Threats

Malware & Computer Viruses

Even if your computer is infected with malware, your private keys remain safe inside the Trézor. Malicious software cannot access or modify your keys because they never leave the secure hardware.

✓ Hardware isolation prevents key extraction

Phishing & Fake Websites

Phishing sites can't steal your funds because every transaction requires physical confirmation on your Trézor device. You'll always see the real destination address on your device screen.

✓ Transaction details verified on device

SIM Swapping & 2FA Bypass

Unlike SMS-based 2FA or authenticator apps, your Trézor cannot be compromised through SIM swapping or phone theft. Your funds remain secure even if your phone is compromised.

✓ Independent of phone security

Physical Theft & Tampering

If your Trézor is stolen, the thief cannot access your funds without your PIN. The device will wipe itself after multiple failed attempts, and the secure element is designed to resist physical attacks.

✓ Tamper-resistant hardware design

Security Best Practices

✓ DO These Things

Verify Every Transaction

Always check the recipient address and amount on your Trézor screen before confirming any transaction. Never rush this step.

Keep Firmware Updated

Install firmware updates promptly to get the latest security improvements and cryptocurrency support.

Use Official Software Only

Only use Trézor Suite or other officially verified applications. Avoid third-party software that claims to work with Trézor.

Secure Your Recovery Seed

Store your recovery seed in multiple secure, offline locations. Consider using metal backup plates for fire/water resistance.

Use Strong PIN

Choose a PIN that's at least 6 digits long and avoid obvious patterns. The longer and more random, the better.

✗ NEVER Do These Things

Share Your Recovery Seed

Never give your recovery seed to anyone, including Trézor support. No legitimate service will ever ask for your seed.

Store Seed Digitally

Don't take photos, screenshots, or store your recovery seed in any digital format. This includes cloud storage, email, or notes apps.

Use Public WiFi for Transactions

Avoid using your Trézor on public or unsecured networks. Use your own secure internet connection for cryptocurrency transactions.

Ignore Security Warnings

If Trézor Suite shows security warnings or alerts, don't ignore them. These warnings are designed to protect your funds.

Buy from Unofficial Sources

Only purchase Trézor devices from official sources. Devices from unofficial sellers may be compromised or counterfeit.

Advanced Security Features

Passphrase Protection

Add an optional passphrase to your recovery seed for an extra layer of security. This creates hidden wallets that are invisible without the passphrase.

Advanced users: Provides plausible deniability

Multi-Signature Wallets

Create wallets that require multiple signatures to authorize transactions. Perfect for shared funds or enhanced security for large amounts.

Requires multiple devices to spend funds

Shamir Backup

Split your recovery seed into multiple shares using Shamir's Secret Sharing. You can recover your wallet with a subset of shares, providing redundancy.

No single point of failure for backup

Coinjoin Privacy

Use built-in Coinjoin features to enhance transaction privacy by mixing your coins with others, making transaction history harder to trace.

Enhanced financial privacy protection

Security Certifications

CC EAL5+ Certified

Common Criteria Evaluation Assurance Level 5+ certification for the secure element chip.

FIPS 140-2 Level 2

Federal Information Processing Standard for cryptographic modules used by government agencies.

Open Source Audited

Continuously audited by security researchers and the global cryptocurrency community.
