Seed phrase,Seed, Recovery phrase, Backup Code, Secret phrase, Mnemonic code or phrase: these are all commonly used names for one of the most important concepts in cryptocurrency security. If you're reading this guide, you should familiarize yourself with wallets and private keys. However, you must also understand seed phrases to back up your crypto assets.
Seed phrases are defined by the BIP39 standard, which is implemented by most crypto wallets.
Your seed phrase can be used to restore your crypto wallet.
Your seed phrase must be backed up and kept secret.
Writing down your seed phrase on paper is not a very robust way to protect it.
An additive "passphrase" could add some security, but it could cause problems - it is an advanced feature with potential pitfalls.
What is a seed phrase or mnemonic code?
In cryptocurrency wallets, the all-important private encryption key is a long string of hexadecimal characters (a mix of letters A through F and numbers zero through nine) that is not possible to memorize, and is tricky to transcribe in any form. For example, "A5CD7462F..." is part of a private key. Instead of having to deal with that long string of characters, the wallet seed phrase, also known as a mnemonic phrase, is made up of 12, 18, or 24 words that the wallet originally relies on to initially generate your private key. The order of the words is critical: if your seed phrase is made up of "State, Tiger, Collect, License...," for instance, they must remain in exactly that order. This seed phrase can be used to back up and later regenerate your private key in case you ever need to restore your wallet.
Seed phrases are part of the BIP39 standard. This is a set of rules that simplify managing private keys via seed phrases. In the BIP39 word dictionary, each word represents a number. When creating a seed phrase, it's important to use a random word generator rather than choosing your own words. A random number generator will ensure that your numbers (and associated words) are chosen more randomly than you could choose, making your seed phrase as secure as possible.
How does a seed phrase protect my crypto assets?
A seed phrase is essentially a backup for your private key. Losing your private key means losing your crypto assets. If you lose access to your crypto wallet, re-entering your exact seed phrase into a new BIP39 software wallet is the only way to get your cryptocurrency back.
Where do I get my seed phrase from?
Hardware, software, and desktop wallets can generate a seed phrase for you, or there are methods that you can use to choose a series of random numbers that can be associated with the BIP39 dictionary. There are a variety of techniques you can employ, including using Vault12 or a random word generator like a mnemonic code utility. Here is a comprehensive list of ways to generate a seed phrase.
How do I use the seed phrase in my digital wallet?
Most digital wallets will have a "Restore from Backup" option, which will ask you to type in your 12, 18, or 24-word seed phrase. Type the words in order, and your assets should be recovered.
You could also add a "passphrase" to your seed phrase. That way, if someone gains access to your seed phrase, your assets have another layer of protection. For wallets that support the addition of passphrases, like the Trezor hardware wallet, passphrases can be long strings and can even include spaces. However, forgetting this passphrase would mean you lose access to your cryptocurrency forever, even if you have the seed phrase. (See section on passphrases in the BIP39 article. Given the added risk of loss, experts do not agree that use of a passphrase is helpful, especially if you are confident in your method for securely storing your seed phrase. Wallet vendors counsel that passphrases should only be used by advanced users. Additionally, not all wallets support passphrases in the same way, so not only do passphrases come with added risks of loss and error in transcription, but they can complicate wallet migration or restoral.
How do I back up my seed phrase?
The most common way to back up a seed phrase is to write it down on a piece of paper - which is not recommended. While it's possible to memorize the phrase, it is very risky to rely on memory for such an important piece of data. Do not retain "extra" or temporary copies of your seed phrase anywhere … each copy must be securely and thoughtfully protected. For more details on how to back up your seed phrase.
