I have used lastpass for several years,and I am (was?) a big fan.
I use LP on both my Android and more on my desktop. Recently when I try to log in on my desktop I get a message, "invalid email or password." I have changed my password but to no avail, same result. I am able to login without problem on my Android. Rather than the Chrome browser I tried using IE and was able to log in. However, switching across the board to IE, for a variety of reasons, won't work for me and signing in on IE does not give me LastPass functionality on chrome. The pain-in-the-rear work around is to sign in on and IE browser, find the password and user name, then copy, go back to chrome and paste into the site.
And things just got weirder: Using Chrome, I found this forum. In order to post this issue here I had to sign in on a sign in box that looks identical to the one used in LastPass. I signed in using my Name and password. Voila, it worked! With gleeful anticipation I pulled up a clean browser and carefully entered my email address and password. It still tells me I am using the wrong email or password.
Please, someone, anyone help!
