DeFi Security
Utilities
Free
DeFi Security App combines a standards-based two-factor authentication app with a read-only monitor for the blockchain addresses you care about.
TWO-FACTOR AUTHENTICATION
Generate time-based one-time passwords (TOTP, RFC 6238) that work with any service supporting 2FA.
- Add accounts by scanning a QR code or entering a setup key manually
- Rotating 6-digit codes generated locally on your device
- Works offline — no connection needed to produce a code
- 2FA secrets are stored encrypted on your device and never sent to our servers
WALLET & ADDRESS ACTIVITY MONITORING
Subscribe to any public blockchain address and follow its on-chain activity.
- Build a personal watchlist of addresses
- View transactions, token transfers and DeFi interactions
- Push notifications when a subscribed address is active
- Your watchlist syncs across your devices
Activity data is aggregated from established on-chain analytics platforms and block explorers through their public APIs. Only public blockchain data is retrieved.
NON-CUSTODIAL AND READ-ONLY
DeFi Security App is not a wallet and not an exchange.
- It never stores private keys or seed phrases
- It never holds or moves funds
- It cannot sign, send, swap or trade anything
- It does not provide investment or financial advice
The app displays public on-chain information and generates local 2FA codes. Nothing more.
GETTING STARTED
The authenticator works right away — no account, no sign-in, no setup. Just add your 2FA accounts and start generating codes.
The monitoring feature uses a free account, which keeps your selected addresses and notification settings synced across your devices.
