Recovery Phrase Backup Planner

The rules that hold at every size

1. Never type it into anything. Not a password manager, not a note, not a document, not an email to yourself. The moment a phrase exists in software it inherits every weakness of that software and of the device it sits on.
2. Never photograph it. Phone photos sync to a cloud within seconds, usually to an account protected by a password you also use elsewhere.
3. Never type it into a page that asks for it. No legitimate service, wallet, exchange or support desk ever needs it. Being asked is the attack, in every case, with no exceptions.
4. Test the backup before you rely on it. An untested backup is a belief, not a plan. Wipe the wallet and restore from your written copy while the amount is still small enough not to matter.

What actually goes wrong

The losses split roughly into three. Phrases that were digitised, so a compromised machine or cloud account took everything. Phrases stored in exactly one place, destroyed by fire, flood, a house move or a clear out. And phrases nobody else could find after the owner died, which is the quietest category and probably the largest.

Notice that only the first is theft. The other two are ordinary life, and they are the ones people plan for least.

The part almost nobody does

Write down where the backup is and how to use it, then tell someone you trust that the note exists. Not the phrase itself, the instructions for finding it. Crypto held perfectly securely and known to nobody is indistinguishable from crypto that was never bought. The hardware wallet chooser covers the device side, and this is the half that outlives you.

Questions people ask

Where is the safest place to store a seed phrase?

Offline, written or stamped by hand, in a place you would keep a passport, with a second copy in a different building. The important word is offline. The moment a phrase exists in a photo, a note, a password manager or an email it inherits every weakness of that software and every weakness of the account holding it, and that is how most losses actually happen.

Can I store my seed phrase in a password manager?

You can and you should not. A password manager is online, syncs to a cloud, and is a target worth breaking into precisely because of what it holds. It also fails in the exact scenario you are protecting against, which is your device or your accounts being compromised. If you own a hardware wallet, putting the phrase into software undoes the entire reason you bought it.

Should I split my seed phrase into parts?

Usually not, and it is a more dangerous idea than it looks. Splitting a phrase in half does not halve the difficulty for an attacker, because knowing half dramatically reduces the search for the rest. It does reliably double your chance of losing access, since either half going missing ends you. If you want genuine splitting, use multisig, which is designed for it and where losing one key is survivable.

What is a passphrase and should I use one?

An extra word or phrase added on top of the twelve or twenty four, creating an entirely separate wallet. Someone who finds your written phrase gets nothing without it. The trade off is unforgiving: forget the passphrase and the funds are gone permanently, with no recovery of any kind. Use one only if you have a genuine plan for remembering it that does not depend on your memory alone.

What happens to my crypto if I die?

Without a plan, nothing happens to it, which is the problem. It stays where it is forever. This is probably the largest category of permanently lost crypto and it gets the least attention. Write down what exists, where the keys are and how to use them, keep it with your will, and rehearse it with the person who would actually have to follow it.

Is a metal backup worth it?

If you are protecting an amount that would hurt to lose, yes. Paper survives neither fire nor flood and both are ordinary events. Stamped or engraved steel costs a small fraction of what it protects and removes an entire category of loss.
