How to Store a Seed Phrase Safely

A recovery phrase — twelve or twenty-four ordinary words — is not a password for your wallet. It is the wallet. Anyone who reads those words controls the funds from anywhere in the world, immediately and irreversibly, and no support desk can undo it.

Why digital copies fail

The most common way people lose crypto is not a sophisticated hack; it is a photograph of a seed phrase in a camera roll that syncs to the cloud, a note in a password manager that was later breached, or a phrase pasted into a chat to "back it up". Anything that touches a network can be copied silently. If your phrase has ever been typed into a device, treat it as exposed and move your funds to a freshly generated wallet.

Physical backups done properly

Write the words by hand, in order, on paper — or better, stamp them into a steel plate designed for the purpose. Paper survives most things except fire and water; steel survives both. Record the wallet type and the derivation details if your wallet shows them, because a phrase without knowing what software created it can be slow to restore. Never store the backup with the device it belongs to.

Splitting and duplicating

Two backups in two separate locations protects against fire, flood and theft far better than one perfect copy in a safe. Resist the temptation to invent your own splitting scheme — cutting a phrase into halves stored apart weakens it more than most people expect, because it also multiplies the ways you can lock yourself out permanently. If you want a formal split, use a scheme your wallet explicitly supports.

The phishing rule

No legitimate wallet, exchange, support agent or "validation" page will ever ask for your recovery phrase. Not to fix a stuck transaction, not to claim an airdrop, not to migrate to a new version. There are no exceptions, which makes this the single easiest rule in crypto security: the moment something asks for the phrase, it is an attack.
