Security and Transparency in Trezor Suite

Trezor Suite combines military-grade security with complete transparency. Open-source code and rigorous security practices ensure you have full control and visibility.

Open-Source Commitment

Trezor Suite is fully open-source software. This means:

Code Transparency

Source Code Available: All code is publicly available on GitHub
Independent Audits: Security experts can review and audit the code
Community Contributions: Developers worldwide can suggest improvements
Verification: Users can verify that the software they use matches the published source code

Security Through Transparency

Potential vulnerabilities are discovered and fixed publicly
No hidden functionality can be inserted into the code
Regular security reviews by independent researchers
Bug bounty programs reward security researchers who find issues

Firmware Updates

Safe Update Process

Update Availability: Trezor Suite notifies you of available firmware updates
Device Connection: You connect your Trezor to your computer
Update Review: You can review update details before installation
Physical Confirmation: You must physically approve the update on your hardware wallet
Secure Installation: The update is securely installed on your device

Update Protection

Updates cannot be installed without physical confirmation on the device
No remote actor can force an update without your knowledge
Update process is encrypted and verified
Older firmware versions remain functional if needed

Hardware Authentication

Device Verification

When you connect a Trezor to Trezor Suite:

Authenticity Check: The software verifies the connected device is genuine Trezor hardware
Bootloader Verification: Confirms the device firmware hasn't been tampered with
Secure Communication: Data between Suite and device is encrypted
Protection Against Counterfeits: Prevents using fake or modified hardware wallets

Why This Matters

Counterfeit Trezor devices could bypass security features. The authenticity verification ensures you're using legitimate Trezor-manufactured hardware.

Security Best Practices with Trezor Suite

Recovery Phrase Protection

Write your 24-word recovery phrase on the backup card
Store it in a physically secure location (safe, safety deposit box)
