Logging into Services with more than one Microsoft Account
You may have seen the error popup if you try to log into say, Schoology, on a non-csu device. It will state theres an issue with authentication and won’t even give you the option to sign back out:
For Schoology specifically:
navigate to Schoology.com rather than clarkssummitu.schoology.com
Log in with the correct account
Refresh
Go to clarkssummitu.schoology.com and it should automatically sign you in correctly.
