Old blockchain.com wallets (I mean wallets before they started to use BIP39 seeds) can be recovered using the link below.
As I said, those 16 words are a blockchain.com password recovery phrase. They will let him recover the password to log in to his blockchain.com wallet, but he will still need the blockchain.com wallet .json file backed up to import, since blockchain.com doesn't seem to store old wallet files anymore based on the dozens of users who have been unable to log in to old wallets without their wallet file backed up.
It also won't let him recovery his
wallet, only his log in details. Should blockchain.com disappear, his coins are lost forever.
When I set up Blockchain originally, they sent me an email, which I still have: "Attached to this email is an AES encrypted wallet backup which contains everything you need to restore your bitcoin balance. You can use it to restore the wallet at anytime at My Wallet or using the 3rd party MultiBit Desktop client."
I have moved my Bitcoins out of my Blockchain wallet, but I am going to keep access to it anyway, just in case.
One thing that confuses me on Blockchain is when I go into "wallets" -- I have a very small amount of XLM -- when I press on the Stellar wallet, the following message comes up:
View Your Private Keys.
Warning
Do not share your private keys with anyone. We will never ask for them. Sharing your keys may result in a loss of funds.
ShowWhy should this message be coming up, when it never did with my Bitcoin or Bitcoin Cash (the only other cryptos I once had there)? I have never clicked on "show", because I know my private key anyway myself. Is this innocent? I would like to move my XLM out of Blockchain (although it is only a tiny amount).
