Why this big change?
For over a year now, INCOSE has been working to transition from one association management system to a different one. Now that the new one is in place, members must do the one-time set up described above to access the new system. All of your member information has been moved to the new system. The new system will provide INCOSE new functionality, and new system integration capabilities and you'll be seeing those in coming weeks and months.
Does this all affect my INCOSE Microsoft account--the one I used to sign into Yammer, Teams or INCOSE Email?
Not at all. Your INCOSE Microsoft Account has a different login username (usually firstname.lastname@example.org) and a different password.
Do I have to verify my account every time I log in?
No, this is a one-time verification. After you will login seamlessly, every time.
