old blockchain.info mnemonic (passphrase) - I LOST ALL?

[gbola]

I need HELP.
Recently i fund some really old (i think from 2014 when blockchain.info started) mnemonic (passphrase)
In that time all my family was bitcoin enthusiast, so i have 5 mnemonic (passphrase) from 5 old blockchain wallets.
Absolutly all was deleted, so i forgot the wallet id and password (in that time blockchain.info not requested attached email for accounts)
The problem is that this mnemonic (passphrase) are not standard like 12 or 24 words seed + the words are not from the standard words list.
My mnemonic (passphrase) have different lengt, like 14, 17, 19 words
From my research blockchain.info in that time, at begin dont used standard words and standard longs seeds ... as i understanded his mnemonic (passphrase) was only to "decode" wallet id and password.
With the new technic bip39 master and blockchain.info account and password recovery i can do nothing   ..
Blockchain support not answer at all, seems they dont want help me
Any help?

Mnemonic phrase are not passphrase, passphrase are passwords used to protect seed phrase, and to every passphrase generated from the same seed phrase, a different seed is generated.

As for the question, I am still new to wallets and BIP but with all your explanation, you have nothing you remember to even recover back the wallet, no email, even the phrase is not remembered, you may not be able to recover back your wallet unless you did the private key backup.

If you did the private keys backup, you will be able to recover back the coin using the private key on a newly created bitcoin wallet.

As you say, these are not BIP39 seed phrases but rather sound like the old style blockchain.info specific recovery phrases.

Have you tried inputting them to their old wallet recovery tool? Link here: https://login.blockchain.com/wallet/recover-wallet

the initial set of words that blockchain.info gave its users had nothing to do with the key pairs the wallet generated, in other words it had nothing to do with HD wallets or BIP0-39 or any other similar key derivation protocol.
it was simply an account recovery phrase and as a result in order to get your account back you can only go back to blockchain.info recovery page or try contacting their support since they are the only ones who can help you.

yes, you have right only blockchain.info support could be help ... but they leave us alone, no help, no support for his OLD SHIT ...

and yes you have right my mnemonic is from before this new implementation - at that time the mnemonic = long passphrase was used by blockchain ONLY to decode/decrypt wallet id and password - has NOTHING to do with the private keys

EXPECT HELP FROM A OLD BLOCKCHAIN.INFO DEVELOPER OR SUPPORT .. shame him, that he leave a lot of his old = fisrt members alone with this problem

Using capital letters will not help someone hear or understand you better, and especially will not affect those behind the blockchain.com project (ex.info). From the very beginning, people think they should trust so-called crypto banks, and we’re talking about Bitcoin as a decentralized cryptocurrency. After so many years, you expect someone to give you something back, and based on what? On having something that looks like a seed or a password?

If the advice from the above posts can't help you, and if you don't get an official response from the support, you have no choice but to accept the loss.

So what happens when you type your words in to this page? Do you get an error? What does the error say?

Do you have any of the old associated aes.json files? Do you still have access to the email account(s) which would have been associated with those wallets? Blockchain.info used to email out the aes.json files as back ups.

in 2014 for blockchain.info accounts was not necessay to have email attached, so i dont have any email attached to this accounts
+at that time they dont provided backup service to can download or request via email your wallet.dat

Lucius .. now is easy to say why i truted him in 2014, but if member with bitcoin from begin, from 2014 for sure remember at that time dont was other safe alternative for bitcoin WEB wallet

And my beginning goes back to 2014, but it never occurred to me to use a web wallet when there were alternatives in the form of desktop wallets. I started with BitcoinCore, then switched to MultibClassic, then to Electrum and finally to hardware wallet. You may have had some specific reason to use an online wallet, but you were certainly not aware of the risks that this entails.

I'm sorry you have a problem like this, and I hope there's a solution - maybe someone will come up with an idea how to access your account.

In which case I'm afraid you are out of luck. The phrases which you have are simply encodings of the hashes of the passwords you used for the wallets. They are a password recovery tool, nothing more. If you do not have the wallet ID, an email address linked to the wallet, or the aes.json file backed up, then you have no way of accessing your old wallets.

You can try to keep harassing blockchain.com support about it (they are awful and will take weeks to respond), but it is unlikely they will be able to help if you can't provide any more details about the wallets in question.

exactly, i know that ..but i really cant understand why blockchain.info in they play fair and correctly and dont want scam his first members why the hell dont offer this "tool" , why they dont keep online this account recovery option - in my opinion in my case are for sure thousand of accounts with many thousands of btc on it!

probably because such tool can not be released since it uses their database. for example it may be something like this: you send them the recovery phrase, they hash it or convert it, or whatever then use the result to lookup in their closed database (that can not be revealed) to fetch something like your email address and the login password salted hash. then it could as for more info and send a recovery link to that email.
no "tool" can be released for this. that's why i said their support is the only one that can help you.

[o_e_l_e_o]

why the hell dont offer this "tool" , why they dont keep online this account recovery option

Because your phrase is not an account recovery tool - it is a password hash recovery tool. It does not tell you your password, but it does tell you what the hash of your password is. It does not link to any account or wallet, and so if you do not have the wallet ID or associated email address, then even decoding your phrase to your password hash would be useless to you.

As pooya87 has said, they are not going to release a tool which requires access to their database. Even if you contact them directly with your phrases, I doubt very much they will scan their entire database for a match and then just hand over control of the wallet to you without any further confirmation (such as a wallet ID or email address which you cannot provide). It would be like me emailing Coinbase and saying "If there's an account with the password xxxxxx then it's definitely mine, can you hand it over please?"

I decided to stop using the blockchain.info (before they bought the domain blockchain.com and directed blockchain.info to that one). I did not have much bitcoin in my old blockchain.info wallet and I was a newbie. It is my fault sure when I did not carefully back up my wallet password and my 2FA secret code for that wallet.

I remembered I only backed up wallet ID, and believed that I always remember wallet password. After months I did not frequently log in wallet, I forgot the password, that is so stupid.

Another stupid thing I do is my phone got technical problems and need to recovered to the pure status. I lost both password and 2FA secret code. I lost the wallet.

I read that people can brute force wallet from wallet id and some good combinations of characters in password.

From the lose, I decided to use non-custodial wallets only.

Do you not have your 12 word seed (or old style blockchain.com password recovery phrase) backed up?

If you still have the email account which was linked to that wallet, you can use that and your wallet ID to reset your lost 2FA. However, blockchain.com say they do not have the ability to reset passwords, so the only option available to you if you don't have your recovery phrase is to try to brute force it. If you have some idea of what the password could be then it might be possible - if you have no idea at all then it may be impossible depending on how long your password was.

If you don't fancy doing this yourself, you can pay a trusted service such as https://www.walletrecoveryservices.com/ to try to brute force it for you. It might not be worth the price though if, as you say, there isn't much inside the wallet.
