Only matching 8 words makes it seem like a lost cause though, since in that case the extended word list would have to be huge. I will ask his other family, maybe somebody helped him set this up and he forgot to add their name. Otherwise let me know if there are other words lists I can try.
Go to this word list and check if each of those 32 words has a match in this list; old Blockchain.info word list:
archive.orgIf matched, it's an old "
Blockchain.info" wallet 'walletid and password' recovery phrase which can be restored here:
login.blockchain.com/wallet/recover-walletHowever, you'll also need to have access to the email address associated with the account for login authentication and recovery purposes.
I started testing the recover wallet link you sent to see if it would be able to recover the wallet id. I did check 10 times to make sure the certificate of the website looked valid etc..and only typed the first two or three words. The first two words were recognised..but the third word was not. I tested with other words from the version 2 version of the dictionary and they also worked. It seems the link only supports version 2 words and not version 3, or there is some way to indicate to it that is a versions mnemonic that I am unaware of.
Or maybe there is another URL for version3 recovery.
I will keep looking though.
We have gotten access to his Gmail email address.somce he wrote down the password. But that wasn't the one used for his blockchain account. So now we are trying to get access to an iCloud email. But will have to reset that password. I must say apple password reset is a monster.
