Comment 3 for bug 1266226

I worked around this issue with these instructions: https://one.ubuntu.com/help/faq/what-should-i-do-if-authentication-fails-auth_failed-state/

needless to say, I didn't manually remove my computer synchronization... it seems suspicious to me that the web interface shows exactly 10 devices (some of these were devices I reinstalled from scratch), maybe there's an hardcoded limit and by adding new devices old ones might get deactivated? (weird, since it should prefer devices that haven't logged in months, not my main computer)

Also, using seahorse is easy enough, but the ubuntu one preferences should handle this automatically (or at the very least let the user know where this information is stored)
