You can contact the support, they will ask you some account releated questioms that only you can answer and they will then be able to reset your account for you

If you contact support, they will message you asking for info like apron date of registration, recent transactions and amounts, and if they are correct then they should let you back in.

Those infos are too easy to get if you have the email.
Also, quote from https://blockchain.info/wallet/security .

Contact their support.  They will sent the hint to your email (but won't reset your account or let you back in without the password).
You can recover the funds using the 12-words passphrase too, btw.

yeah using the Mnemonic phrase, but you must contact the administration if your lost your email that associated with that account, of course with any secret information like secret phrase or alias

according to their blog https://blog.blockchain.com/2015/03/17/whats-the-difference-a-comparison-between-key-blockchain-wallet-terms-and-features/#sthash.kRhvW9CM.dpuf

"A mnemonic is the passphrase seed of your Blockchain Wallet provided to you when you sign up for a new wallet. The purpose of this is in case you need to recover your wallet at a later date, if you lose your login information. When you recover your wallet with your mnemonic, your password and identifier will be displayed to you. Your main password can not be changed once it is set, therefore your mnemonic will always remain the same for each wallet. To find your wallet mnemonic, log into your Blockchain wallet, Account Settings, and click on Passwords."

Nah, it's not like a private key that you can move your funds to another wallet, but it's clearly aims to recover your wallet on blockcahin.info when you lose your login information through this link https://blockchain.info/wallet/recover, the passpharse is generated when you sign up for new wallet.

You can access again to your blockchain wallet if you have the passphrase in the security tab of your account, even if you lost you email account, forgot your password and your wallet ID if you have the 12 passphrase gave by blockchain to you for security purposes well you can open your account again. But if no, well try to contact their support maybe they can give back your account if you convince that you are really the owner of that account.

I think OP don't have much than just a password hint, and i am sure blockchain don't store any of the user passwords as all encryption and decryption is done on server side for better security. And even you contact support they will only suggest you to try to remember your password looking at hint.

Op, you lost your password but you know your identifier? For me identifier is harder to remember than my password.

Also this:

I thought I might be able to help out a little bit here...

To download the (encrypted) wallet from blockchain.info, run this from the command line (Linux or Windows, but for Windows you need to install Python 2.x first).

Code:

python -c "import urllib2,json;f=urllib2.urlopen('https://blockchain.info/wallet/9bb4c672-563e-4806-9012-a3e8f86a0eca?format=json');print json.loads(f.read())['payload']" > wallet.json.aes

(Obviously you'll need to change the UUID to match yours first.)

For brute-forcing the password, I'd recommend one of two options.

If the downloaded file doesn't start with these two characters: {" , and if you've created or modified (e.g. added new receiving addresses) to it at sometime after March, 2012 (when the wallet format changed again), and if you're on (or have easy access to) Linux and are comfortable compiling software, then I'd recommend John the Ripper ("bleeding-jumbo" version). It's faster than the alternative (and much faster with a GPU).

Otherwise, I'd recommend btcrecover (course I'm biased since I'm the dev of that one...). It supports some blockchain.info wallet formats that JtR doesn't, and it's easier to set up (no compilation necessary), especially on Windows. The Quick Start is available here: https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial. Let me know if you have any questions about it...

And maybe this thread will be of any help if you won't find your password, it is Password Recovery Service:

This is correct -- Blockchain.info doesn't actually store your password, so they have no way provide it to you.  They also can't just move your funds to a new account, because they can't move your funds without knowing your password.  (That's the beauty -- and occasionally the curse -- of the distributed ledger).

Your best bet to recover your password is to be persistent and methodical in trying to guess your password.  We just published an article on how to do that -- I hope it's helpful. https://cryptoassetrecovery.com/blog/recover-lost-blockchain-password/

Hello i have lost my password on blockchain.info what can i do?

Thanks you

1. Blockchain.info doesn't  store your password.
2. only private key and 12 words will help you to back your access.
3. use your email to get your wallet id "like username"
4. if you use an easy password and know part of password ask a trusted member to crack your wallet.
