How safe is "save password" in the Lync client? RRS feed

  • Question

  • Hello,

    I would like to know what happens when a user clicks "save password" in the Lync client. Is the password stored on the PC?  If the password is stored on the PC, is this "safe"?

  • Hi

    It is "safe" if the PC its stored on is safe. Do you run windows update regularly, is the firewall on, is the hard drive encrypted and so on.

  • Hi,Herman,

    Authentication in Lync is performed with certificates and the communication is using  TLS  encryption , an attacker would not have a valid certificate required to autentication in the communication,even though they successfully attack the password they can not be allowed to access Lync on a computer which didn't acquire the certificate from your Lync server.

    Of course, it is impossible to design against all unknown security threats.You need keep running windows update,configure firewall and real-time monitor your system security,etc.Make sure your PC in a "safety" status will keep far away unsecure threats for Lync.

    More details about Lync client security you can look at  http://technet.microsoft.com/en-us/library/gg195618.aspx

  • Hello Sharon,

    Thanks for the answer.

    But if the client uses certificates for authentication, why is the password then stored?

  • Technically, the password is never stored, a hash of it, does.
