Related Terms in Security & Privacy

Private Key Security
The practice of protecting your cryptocurrency private keys from theft, loss, and unauthorized access. Includes hardware wallets, encrypted backups, physical security, and operational security protocols.
Seed Phrase Backup
Securely storing your wallet's recovery phrase offline. Best practices include metal backups (fire/water resistant), multiple locations, and never storing digitally. Losing your seed phrase means losing access permanently.
Hardware Wallet
A physical device storing private keys offline in a secure element chip. Transactions are signed on-device and never expose keys to the internet. Ledger, Trezor, and Keystone are leading brands.
Air-Gapped Wallet
A wallet on a device with no network connectivity — no WiFi, Bluetooth, or USB data. Signs transactions via QR codes or microSD cards. The highest security level for crypto storage.
Multi-Sig
A wallet requiring multiple private key signatures to authorize transactions. Common configurations: 2-of-3, 3-of-5. Eliminates single points of failure. Used by DAOs, exchanges, and security-conscious individuals.
2FA
Two-Factor Authentication — requiring a second verification method beyond your password. TOTP apps (Google Authenticator, Authy) generate time-based codes. Essential security for all crypto exchange accounts.
TOTP
Time-based One-Time Password — a 2FA method generating 6-digit codes that change every 30 seconds. More secure than SMS-based 2FA because it's not vulnerable to SIM swap attacks.
YubiKey
A physical security key providing hardware-based 2FA via USB or NFC. Phishing-resistant because authentication requires physical presence of the key. The gold standard for account security.
