Multi-Factor Authentication (MFA)

Tychi Wallet implements Multi-Factor Authentication to safeguard user accounts, sensitive wallet actions, and identity modules—ensuring robust protection without compromising user experience.

🔒 Why MFA Matters

With increasing threats across Web3, single-factor login mechanisms (like passwords) are no longer sufficient. Tychi adopts MFA to add multiple layers of identity verification before allowing wallet access or transaction approvals.

✅ Authentication Factors Used

1. Something You Know

   • Secure password or passphrase

   • PIN for quick wallet-level confirmations

2. Something You Are

   • Biometric verification (fingerprint or facial recognition)

   • Device-native biometric APIs ensure privacy and speed

3. Something You Have

   • Time-based One-Time Password (TOTP) via Google Authenticator or Authy

   • Hardware tokens (e.g., YubiKey) for advanced users (optional)

🧠 MFA Usage Within Tychi

• Login Protection Requires at least two factors (e.g., password + biometric) for app/device access.

• Transaction Approval High-risk actions (e.g., large transfers, DApp authorizations) require full MFA confirmation.

• Cold Wallet Access Mandatory MFA required to view or export cold wallet private key access controls.

• Identity Verification MFA required when accessing DID documents or issuing Verifiable Credentials (VCs).
