[SECURITY VULNERABILITY] - Connecting to online services UNKNOWN ERROR

This doeeees blow a hole in it. RIP. 
Unless there is a difference in the authentication methods used the first time a user logs in vs. subsequent log ins? 
eg. First log in you select the ID/password, subsequent log ins revert to a seperate ID/password combination

It’s difficult to say for certain. But multiple ID’s used for account authentication is still probably something EA should be willing to investigate
