with blockchain.info there are two different things you may be calling unique ID!
1. your
Wallet ID:
acts as your username to log in your wallet and you should not share that with anyone:

that is a series of letters numbers and dashes:
########-####-####-####-############
2. your
recovery phrase aka Seed:
which you absolutely shouldn't share with anyone because that can be used to directly gain access to your funds.
that is a series of words (i think it is 13)
sorry , my mistakes. that's what I'm talking about "wallet ID".
I had a case that someone had my wallet ID in blockchain. when he accessed my wallet there is no notifications in my email and when he sent my bitcoin to the other bitcoin wallet there is no notifications either.
normally when we accessed and sent the bitcoin, of course we will get the the notification. in my case 0.21 BTC has stolen.
the question is, Whether blockchain can be accessed through CMD ?
