Missing 4 words is not much, could be brute-forced. Do you know the address?
What kind of address do you mean?
Not good news for you. Have you tried to contact with their support? Maybe they can help you to recover the password.
my problem is I have lost my secondary password used for withdrawal.
They will definitely have a way to recover this.
Yes and this is their reply:
Hello,
Unfortunately we are unable to help recover or reset passwords. This is not a matter of policy. This is due to the very way the file encryption is designed. Please try every possible password combination you may have used.
If you backed up your wallet via the 12 word recovery phrase, then you can recover your funds here -
https://login.blockchain.com/#/recover. If the Continue button is inactive, then the recovery phrase submitted is inaccurate. Please be aware any funds or addresses stored within the Imported Addresses section of the wallet will not be restored.
If you do not have the correct password or an accurate recovery phrase, then access to the wallet and any funds it may contain has been lost.
I just created a new wallet on blockchain. It didn't ask me to set a secondary password. I also checked the security section and couldn't find anything related to secondary password.
So, I guess you have an old wallet created before their upgrade. If so, read the following topic. It may help you.
To those who lost their Blockchain.info Secondary Password..Yes I have created my account at Nov 29, 2017. I have the welcome email.
I checked this topic but I could not find any jason file in my emails.
So you are able to login to your Blockchain.com wallet, but you can't spend or withdraw any of your coins? Correct me if I'm wrong.
Assuming that your partial seed phrase is for your bitcoin balance, and not for ethereum, the best solution is to use the seedrecover.py script from
btcrecover to guess the last 4 words of your seed phrase. Since you have the list of addresses in your wallet, you can supply them to seedrecover.py along with the words of your seed phrase to speed up searching, with detailed instructions at
https://github.com/3rdIteration/btcrecover/blob/master/docs/Seedrecover_Quick_Start_Guide.mdYou can also get your xpub (master public key) from Blockchain.com and supply that to seedrecover.py to help it guess the rest of the words in your seed phrase. In fact xpub is preferred over giving it your addresses so if you have your xpub, then just give it that, and it won't ask for your addresses.
Sorry I can not login. after I enter my main password the site asks for the secondary password:
