Surfy version 5.4 gets Passcode Authentication

[KatkaV]

While Surfy already includes an effective in-private browsing mode, Surfy now goes further to protect your browsing from prying eyes by allowing you to set a login passcode, which is displayed when you launch Surfy or leave your phone unattended for more than several minutes. The passcode is set from the Privacy section of the options screen within Surfy.

Surfy version 5.4 also brings in support for the Kannada language. Although Windows Phone does not natively support Kannada, it is available in Surfy via the Language drop-down on the options screen.
