What is a Recovery Seed?

Your recovery seed (also known as bitcoin seed, seed phrase, recovery phrase, mnemonic seed, wallet backup, etc.) is an ordered set of 12-24 words that is randomly generated by your wallet. It stores the information that can be used to recover your wallet and coins when your wallet fails unexpectedly (such as damage, unable to access, misplaced, theft, etc). Ensure it is hidden in a secure location and stored/written on something that will last your lifetime.

Blockplate uses an innovative, single-tool method to store your recovery seed on strong, durable steel. It has been third party tested and proven to be the fastest and simplest way to protect your recovery seed with long lasting metal.

Introduction To Your Recovery Seed

You've chosen a wallet to store your Bitcoin. It is either a hardware wallet (like a Trezor or Ledger) or software wallet on your mobile phone or desktop computer.

When starting your wallet, it gave you a 12 or 24 word phrase of seemingly random words in a specific order. 

This phrase is known as your wallet's recovery seed. It can also goes by recovery phrase, seed phrase, mnemonic phrase, wallet seed, etc. (some combination of the words: "wallet","recovery", "seed", "phrase" but we're going to use recovery seed)

Your wallet also might have informed you to write your recovery seed down somewhere secure. In the event the device your wallet gets lost, broken, destroyed, corrupted, stolen, etc. your recovery seed is the one thing that can restore and recover your wallet and coins on another device. (Think of it like a map to your coins)

And remember, not only the words themselves are important but the order of the words are equally as important.

Recovering Your Wallet

You're able to input your recovery seed into ANY wallet that uses the "same type" of recovery seed to recover your coins on that device.

What does it mean by "same type"? It doesn't mean same number of words.

It means the method and format that wallet used to create your recovery seed.

The method and format is described in a Bitcoin Improvement Proposal (BIP). BIP's are various "features" and "rules" of Bitcoin. They are designated by a specific number. Topics of these BIP's can vary widely.

The topic of recovery seeds fall under Bitcoin Improvement Proposal: 39 (BIP 39). It describes the method your wallet creates a mnemonic phrase -- a group of easy to remember words -- that is the link to your coins.

If the wallet knows the method your recovery seed was created (in this case BIP 39), it can be used to recover your coins in the event your wallet becomes compromised.

This format also includes a specific list of 2048 words (known as the BIP 39 wordlist) that the words in your recovery seed is pulled from.

Luckily, many wallets use BIP 39 to generate recovery seeds. Any of these wallets can be used to recover your wallet. (If you're wondering if your wallet uses BIP 39, search your wallet name and the term "BIP39" in the search engine of your choice to find its documentation.)

Different wallets have different instructions for recovering a wallet but in general, you're going to be typing/choosing words in the specific order of your recovery seed to re-generate your wallet on that new device/software.

Can Someone Guess My Recovery Seed?

Remember when we said that your recovery seed comes from a specific list of 2048 words. Someone would have to guess all the words AND put them in the correct order. There are 340,282,366,920,938,463,463,374,607,431,768,211,456 possible combinations for a 12 word recovery seed. Even more combinations for a 24 word recovery seed. 

In other words, it ain't going to happen anytime soon.

But the number of combinations decreases the more words someone one else knows. Thus, it is important that you keep your recovery seed hidden and secret.

Recovery Seed Security

You can use your recovery seed to generate and re-generate your wallet as many times as you want and in as many devices as you want (Yes, your wallet can be on more than one device at one time)

Pretty nifty huh? Those 12-24 words are the link to your coins that you can take literally anywhere and can last forever. You should think of your recovery seed as your wallet.

Thus, it is imperative that how ever you store or write your recovery seed, it is not only hidden but will last.

There have been many instances of people making headlines by losing bitcoin:

Don't be one of them. Seriously.

Over 4 million bitcoin (20% of total circulation) have been lost forever. Don't add yours to that.

Not only are you protecting your recovery seed against other people, you're protecting your recovery seed from your own stupidity (yes, we're all just a little stupid sometimes), natural occurrences (like pests, flooding, fires, and storms), and the test of time.

Time includes physical deterioration such as corrosion and fading; and mental deterioration such as forgetfulness.

So again, make sure your recovery seed is written down or stored on something that you'll be able to access for a long time.

That means it has to be durable and at the same time accessible. (That doesn't mean to bury your recovery seed 6 ft into the ground. You are storing your recovery seed for your future self. Don't make them mad.

Securing your recovery seed is a job that requires common sense and thoughtfulness. It is important that you do as much as you need to in order to not only feel safe but confident in accessing your recovery seed in the future when you need it.

We've written a few topics on recovery seed preservation and security:

Recovery Seeds Stored On Metal

We recommend storing your recovery seed on something physical like paper or metal. Why? Because it is not connected to something than can be hacked and can last a really long time.

When we say "stored on metal" we really mean "written on metal". Metal such as stainless steel or titanium are great materials for longevity and durability of your recovery seed (more so than paper). Metal protects your recovery seed from wear and tear, heat/fire, and water/corrosion damage.

Blockplate uses an innovative method to securely store offline your recovery seed on durable, long-lasting steel.

It has been tested against the competition and proven not only to be indestructible but the absolute simplest way to store your recovery seed on metal.
