Can't login, password reset doesn't help
Open https://extensions.gnome.org/accounts/login and try to login using either form in the center of the page, or in top-right corner of the page.
Try to login with your username and password. It doesn't work.
Try to reset the password and login again. It doesn't work.
Possible reason (can be seen in Chrome console):
Found 2 elements with non-unique id
#id_password
: (More info: https://goo.gl/9p2vKq)
same for #id_username
