I wanted to provide someone at AgileBits the information that I've discovered that the 1Password extension in Safari or Chrome seems to interfere with the 'change password' page that University of Southern California is now using for all of their students and staff at: usc.edu/changepassword.
I have no idea what secret sauce they are using for their form, but somehow when you attempt to input the correct password using this form, it is always rejected as wrong, even when not using 1Password — the extension simply has to be enabled for the issue to occur. I have thoroughly cleaned caches, cookies, etc., but toggling 1Password extension off cures the problem in both Safari and Chrome, and reenabling the extension brings the problem back.
I don't know if you can do anything without a login to the site, but if you contact me offline, I can help troubleshoot, if you'd like.
1Password Version: 5.3
Extension Version: 4.4.0.b7
OS Version: 10.10.4
