When you create a wallet in Quantum, your device generates a recovery phrase: 12 or 24 ordinary words in a specific order. That phrase is a human-readable version of your private key, and it is the only way to restore your wallet if your phone is lost, stolen or broken. Because Quantum is non-custodial, we never see or store it — which protects you from hacks and frozen accounts, but also means nobody can reset it for you. The golden rules are simple. Write the words down on paper, in order, the moment you create your wallet. Check each word twice. Store the paper somewhere private and protected from fire and water, and consider a second copy in a different secure location. For large balances, a metal backup plate is a worthwhile upgrade.
