Wallet Security Basics: Seed Phrases, Private Keys, and What Never to Share

Your recovery information is the master key to your wallet. Treat it like cash, not like a password reset question.

Know what you are protecting

A seed phrase (also called a recovery phrase) can recreate a wallet and usually controls every asset in it. A private key controls a specific address. A wallet password may protect only the app on one device. Losing access to any of these can be serious; sharing a seed phrase or private key can give someone else full control.

What never to share

  • Seed or recovery phrases—even one word at a time.
  • Private keys, keystore files, or recovery codes.
  • Screen shares that expose recovery information.
  • Photos, cloud notes, or copied text containing wallet secrets.

No legitimate support agent needs these to diagnose a wallet, verify an account, or “sync” funds.

Safer backup habits

  1. Write the recovery information down offline, accurately, and in the correct order.
  2. Keep it somewhere private and protected from fire, water, and casual access.
  3. Do not store it in email, chat, screenshots, cloud drives, or a browser extension.
  4. Before moving a large balance, verify that you understand the wallet’s documented recovery process.

Before approving anything

Read what a wallet is asking you to sign. A transaction or token approval can have consequences beyond a login. If the site, request, or timing feels wrong, stop and independently verify the destination first.
