Account access issues

I had trouble accessing accounts at NCU yesterday. My delay in accessing/setting up the new NCUOne account may be the cause. Today, I logged into the new NCU One account, accepted a new course, and so on. Then, I tried to login using the old way and could not. My guess is that the university implemented single sign-on (I sent an email. I should learn more soon.).
