Background: I have an institutional account which uses an SSO powered by Duo security. So every time I sign in to my account, there's a multi-factor authentication (MFA) prompt that sends a push notification to my mobile device, which I'm supposed to authorize to gain access to my account.
Issue: I use Acrobat Pro on my Mac. I can sign in to my Adobe account through the institutional ID on Acrobat. I enter my institutional domain, sign in with the SSO, wait for the MFA prompt, authorize the push notification, it all works fine. However, when I try adding my google drive account (which uses the same institutional account, hence the same SSO), the MFA prompt does not show up. Consequently, I am not able to log in.
I am not sure if I understood correctly but, are you saying that you're using the same credentials to sign in two different cloud services at the same time. Is this what you're doing? Same username and same password for both cloud services?
