🔐 Step 5: Backup Your Recovery Seed

THE MOST IMPORTANT STEP IN SETUP

What is a Recovery Seed?
Your recovery seed is a human-readable representation of your private keys. It allows you to recover your entire wallet if your device is lost, stolen, or damaged.

Proper Backup Protocol:

Do:
✓ Write words in exact order provided
✓ Use provided recovery cards or archival-quality paper
✓ Store in multiple secure locations
✓ Consider fireproof/waterproof metal backup
✓ Verify backup accuracy immediately

Never:
✗ Type into computer or phone
✗ Take photos or screenshots
✗ Store in cloud services or email
✗ Share with anyone
✗ Use pre-printed seed phrases

Seed Generation Process:

  1. Device displays words on its screen only

  2. Write word #1 on recovery card space #1

  3. Continue sequentially through all words

  4. Double-check order and spelling

  5. Complete verification in next step

Security Consideration:
If you see pre-populated words or someone offers you a seed phrase, your device may be compromised. Contact support immediately.

✅ Step 6: Verify Your Backup

Verification Process:

  1. Trezor Suite will prompt for verification

  2. Device will ask for random words from your seed

  3. Example: "Please enter word #7, then word #2"

  4. Use device buttons/touchscreen to select words

  5. Complete 3-5 random checks

Why Verification is Crucial:

  • Ensures you actually wrote words correctly

  • Confirms you can perform recovery if needed

  • Identifies transcription errors immediately

  • Prevents irreversible asset loss

Failed Verification?
If you cannot verify correctly:

  1. Do not continue

  2. Start setup over from beginning

  3. Pay closer attention to word order

  4. Consider using larger word count (24 vs 12)

🔢 Step 7: Set Up PIN Protection

PIN Security Features:

  • Protects against physical theft

  • Random keypad layout prevents shoulder surfing

  • 1-9 digit length (longer = more secure)

  • Wipes device after 16 incorrect attempts

PIN Creation:

  1. Device displays random number layout

  2. Enter PIN on device screen only

  3. Computer shows different layout for security

  4. Confirm PIN with second entry

  5. Remember: PIN protects device, seed protects funds

PIN Best Practices:

  • Minimum 6 digits recommended

  • Avoid patterns (123456, 000000)

  • Don't use personally identifiable numbers

  • Consider different PINs for multiple devices

🎯 Step 8: Name Your Device

Device Naming:

  1. Choose descriptive name

  2. Examples: "Primary Trezor," "Savings Wallet"

  3. Helps identify multiple devices

  4. Changeable anytime in settings

🚀 Your Trezor is Ready!

❓ Frequently Asked Questions

1. Can I recover my wallet if I lose both my Trezor and recovery seed?

No. Without your recovery seed, your funds are permanently inaccessible. This is intentional security design—if anyone could recover your wallet without the seed, so could attackers. We recommend storing multiple copies of your seed in different secure locations.

2. How many cryptocurrencies does Trezor support?

Trezor supports over 8,000 cryptocurrencies including Bitcoin, Ethereum, ERC-20 tokens, Litecoin, Dogecoin, and most major altcoins. The full list is continuously updated at trezor.io/coins. New coins are regularly added via firmware updates.

3. What's the difference between Trezor Model T, Model One, and Safe 3?

  • Model T: Touchscreen, advanced features, Shamir Backup, more powerful processor

  • Model One: Button-based, essential security features, most affordable

  • Safe 3: Latest security chip, compact design, optional Bitcoin-only firmware
    All models provide the same core security—keeping your private keys offline.

4. Can I use my Trezor with mobile devices?

Yes. Trezor works with:

  • Android via USB OTG cable

  • iPhone/iPad with Trezor Safe 3 (Bluetooth) or via computer bridge

  • Always use official Trezor Suite mobile app

  • Never enter seed into mobile device

5. What happens during a firmware update? Will I lose my funds?

Firmware updates are safe and won't affect your funds if you follow proper procedure. Always ensure you have your recovery seed backed up before updating. The update process preserves your wallet data, but having your seed ensures recovery if anything goes wrong.

6. Is Trezor truly 100% secure?

While no system is 100% secure, Trezor provides the highest practical security for cryptocurrency storage. It protects against remote attacks, malware, and phishing. Physical security depends on your PIN and seed protection. For maximum security, we recommend:

  • Strong PIN (6+ digits)

  • Secure seed storage (multiple locations)

  • Regular firmware updates

  • Passphrase for hidden wallets
