Some famous CRMs love to do this -- prepend a string that varies every time you load the page. Either this is some tenant-identification magic, or something else. I don't know, I just know I've seen it on sites.
The fields above both end with email and password, but a dynamic prefix gets added each time you load the page. In this case, it is c705_. So, you'll have to find a different way of talking to these fields besides just grabbing IDs in DOM directly.
