24JUN2015 I have been a user of LastPass for about three months based on a recommendation on the Kim Kommando web-site/radio show. I have owned a PC since the early 1990's, so I have a bit of computer experience. I am paying customer of LastPass in order to have access to my unique passwords on my mobile phone and to share passwords with family members (handy for banking/financial websites). Regarding the service of LastPass. Within the last week they suspected a data breach, I received an E-mail within 24 hours of the suspected breach (before ***** even reported on it). They suggested I change my master password, then change passwords for all the web-sites I had saved on their service. They reassured me that the "front end data" (user name, email, master password) was separate from the 256bit encrypted passwords which was not likely compromised. I was glad they did not wait to communicate with their customers. I understand that as a password management site they are a prime target, but since they deal with government contracts and offer a paid service, I have confidence that their security measures are top notch and recommend their free or paid service. As for their website, using Win7 with Kaspersky AV and the FireFox browwer with the following Add-0ns, I never get reports of nefarious activity when visiting the website: AdBlocker Plus Ghostery NoScript FlashStopper

A fantastic site. I've been using it for years. Safe and secure. They emailed when the last big threat hit the web... can't quite recall its name. Fantastic. Makes the web more secure.

Last pass is fast and to some degree reliable. The only problems I have had with it were being so fast that I would sign out and get signed back in in the blink of an eye and having multiple passwords for a site. That was before I learned how to use it properly.
