How do I Change Wallet identifier (Blockchain.info) RESOLVED

[Polyatomic]

Polyatomic here ,(RESOLVED)

                     I got an email from Blockchain.info informing me that a "login attempt was made from an unknown browser"

Code:

An attempt to login to your blockchainjnfo wallet was made from an unknown browser. Please confirm the following details are correct:
Time: 2013-07-14 02:20:04 IP Address: 95.105.21.115 (Russian Federation) User Agent: Mozilla/5.0
It this login attempt was made by you this email can be safely ignored however you may wish to change your wallet alias.

How do I change my wallet identifier , also does "login attempt" mean my wallet was actually accessed ? .

                                     Cheers
