Additional Password Security

Thursday, August 25th, 2005

When logging into LuxSci’s standard WebMail portal, users can now optionally use a visual keyboard to enter their password via their mouse rather than typing it in using their regular keyboard. This is be helpful to those using untrusted computers — computers, such as those in Internet Cafes, that may be infected with spyware which could be capturing all of their keystrokes. Use of the visual keyboard can help mitigate the possibility that spyware programs running on your computer could capture your password.
