You will be presented with a screen when you will enter the first 4 of 12 words of your secret phrase. Enter your first 4 words and tap Next. Continue until all words have been entered and tap Restore. After tapping Restore, Exodus will ask you if you are sure. Your word phrase is a set of words randomly taken from a dictionary, with each word assigned to a number. The seed phrase can be converted to a number that is used as the seed integer to a deterministic wallet that generates all the public and private keys. The words are taken from a wordlist of the BIP39 standard ( words). Mar 23, · If you were to lose access to your wallet for whatever reason — a stolen computer, a failed hard drive, or accidental deletion — your word .
Bitcoin 12 wordsSeed phrase - Bitcoin Wiki
I contacted the support group and they told me that I had probably made a mistake. Using Python and this library you can print all the valid ones with this simple script:. Then you can try them one by one to a wallet that support BIP Obviously change the last 11 words in my example with your words. If you are missing just one word from a word seed phrase, and you know the position of the missing word, then chances are you'll be able to recover your wallet.
As Martin mentioned, if you are missing multiple words, or you do not know the position of the missing word, then the number of possible combinations increases greatly, perhaps to the point of it being computationally infeasible. Here is a link to the BIP39 word list. If you remember anything about the word eg, you think it started with an "a" , then you could just manually try recovering a wallet with each word that matches your suspicion in combination with the rest of your seed phrase.
To run the entire list, you'll probably want to automate the process using some software to quickly iterate through the list. If you're referring to "11 Characters" of your Private Key- you are out of luck. Brute-forcing the missing characters is not possible, at least not in today's world. If you're referring to "11 Words" from a Mnemonic Phrase, you are also out of luck. Factoring the astronomical number of possible combinations only a three, four, or five word Mnemonic can contain -, a dictionary attack to hash out the rest of the Mnemonic Phase would be very difficult, with each additional word needed not sure if you had a 15, or 16 word Mnemonic , creating an massively exponential increase in solving using todays computing power.
Missing 1 Word of a Mnemonic, could be dictionary attacked on a modern PC workstation. Missing 2, nearly impossible unless you know how to dictionary attack, have your rainbow tables all ready to go, but 3 words or more? Sign up to join this community.

What can I do? Perry Perry 91 1 1 silver badge 6 6 bronze badges. When you say 'private keys', I assume you actually mean 'mnemonic seed phrase words', right? Private keys are long, random-looking strings of numbers and letters.
Mnemonic seed phrases are composed of regular words. You may find metasafe. Active Oldest Votes. This works by the wallet creating a seed phrase and asking the user for a password. Then both the seed phrase and extra word are required to recover the wallet.
The BIP39 standard defines a way of passphrase-protecting a seed phrase. A similar scheme is also used in the Electrum standard. If a passphrase is not present, an empty string "" is used instead. Warning : Forgetting this password will result in the bitcoin wallet and any contained money being lost.
Do not overestimate your ability to remember passphrases especially when you may not use it very often. Warning : The seed phrase password should not be confused with the password used to encrypt the wallet file on disk. This is probably why many wallets call it an extension word instead of a password.
Most people write down phrases on paper but they can be stored in many other ways such as memorizing , engraving or stamping on metal, writing in the margins of a book, chiseling into a stone tablet or any other creative and inventive way. In the past many people have accidentally lost bitcoins because of failed backups, mistyped letters, forgotten hard drives, or corrupted SSD devices.
It's also important to protect the seed from accidental loss. It could be a good idea to write some words of explanation on the same paper as the seed phrase. If storing for the long term you may forget what a phrase is how it should be treated. A sample explanation that can be adapted is:. Through bitter experience it has been found that one of the most practical storage mediums is pencil and paper.
The private keys of a bitcoin wallet are encoded into random words from a dictionary which can be written down. If your hard drive crashes, you can find the paper with the seed phrase and restore the entire wallet. As seed phrases use natural language words, they have good error correction. If one or two letters are missing the word can often still be deduced. For storing on paper writing with pencil is much better than pen  . Paper should be acid-free or archival paper, and stored in the dark avoiding extremes of heat and moisture   .
Seed phrases can also be stamped or engraved into metal which is significantly more durable than paper. Metal backups are recommended if the threat model involves fire, water, extremes of temperature or physical stress.
Some methods that are not recommended are: storing in a file on a computer including online , or storing online. Some people get the idea to split up their phrases, like storing 6 words in one location and the other 6 words in another location. This is a bad idea and should not be done, because if one set of 6 words is discovered then it becomes far easier to bruteforce the rest of the phrase.
Storing bitcoins in multiple locations like this should be done with multisignature wallets instead. The Shamir Secret Sharing algorithm is sometimes promoted as a way to divide control of bitcoins, but in practice there are many pitfalls and tradeoffs that make it not worth it.
Another bad idea is to add random decoy words that are somehow meaningful to you, and later remove them to be left only with the 12 word phrase.
The phrase words come from a known dictionary see next section , so anybody can use that dictionary to weed out the decoy words. It's possible but risky to memorize Brainwallets seed phrases. This should probably only be done in situations that really need it, such as crossing a hostile border where one expects to be searched. Generally a seed phrase only works with the same wallet software that created it. If storing for a long period of time it's a good idea to write the name of the wallet too.
The BIP39 English word list has each word being uniquely identified by the first four letters, which can be useful when space to write them is scarce. Seed phrases are sometimes called "mnemonic phrases" especially in older literature. This is a bad name because the word mnemonic implies that the phrase should be memorized. It is less misleading to call them seed phrases. An especially interesting aspect in the power of paper backups is allowing your money to be two places at once.
