Someone today tried to gain access at blockchain.info to my wallet, anyone else seeing this attack coming from the UK?
Tried multiple times!
Did you got an email notification about it?
Apart from the above advice of changing identifier, I would also advice you to change your email password and apply 2fa to it.
2fa is not going to help you with blockchain. If an attacker has access to a backup of your wallet all they need is your password (and 2nd password if you have one) to steal your money
