What a recovery phrase actually is (and what it isn’t)

This is the concept to understand before any other, because almost every answer follows from it: why there is no «forgot my password», why nobody can help you reset, and why whoever sees your words takes your money.

What they actually are

When you created the wallet, the program generated an enormous number, chosen at random. All your keys and all your addresses come from it. And so you could write it down without mistakes, it translated it into words: each word represents a chunk of that number.

So your twelve words aren’t a password protecting your wallet: they are the wallet. That isn’t a nuance. A password protects something stored elsewhere; these words are the something.

What they aren’t

  • They aren’t a password. They can’t be changed, can’t be reset, and there is no «forgot my phrase».
  • They aren’t an account. There is no record on any server, no associated email, no support to appeal to.
  • They aren’t a backup of something else. They are the original.
  • They don’t belong to a brand. They work in almost any wallet in the world, not just the one you used.
  • They don’t expire. A 2017 phrase opens exactly the same thing today.

The three consequences that explain everything

  1. Whoever sees them, gets in. From anywhere in the world, without your computer and without your permission. That is why they are never shown, typed into websites or sent by chat.
  2. If you lose them entirely, there is no recovery. It isn’t about price: there is nothing to rebuild. See can a completely lost phrase be recovered?.
  3. If part is missing, it is almost always recoverable. Because the phrase carries an internal check that discards nearly every wrong reconstruction. See what a self-checking phrase means.
That third consequence underpins all my work, and it is what many people don’t know: between «I have it all» and «I lost it completely» there is an enormous middle ground — one word missing, the order unknown, unreadable handwriting, a plate that lost pieces — where something can be done.

Where to keep it

On paper, handwritten, somewhere it won’t get wet or lost, and preferably with a second copy in another physical place. Not in a photo, not in your phone notes, not in the cloud and not in an email. The convenience of having it on your phone is exactly the mechanism by which it gets lost.
