U-M alumni (includes former students who graduated as well as those who did not) and their spouses or same-sex domestic partners (SSDPs).
Retired faculty and staff and their spouses or SSDPs. Note that retired staff receive an ITCS-provided e-mail mailbox at no charge; retirees who do not use other U-M computing services will not need U-M Online. See Frequently Asked Questions About ITCS Services for U-M Retirees for details. Emeritus/Emerita faculty may continue using Basic Computing Package (BCP) services at no charge and therefore do not need U-M Online. For details, see 19.K Emeritus/Emerita Status in the U-M Faculty Handbook.
Spouses and SSDPs of current faculty, staff, and "Active in Program" students.
Sorry, but no. Children of people in the categories above are not eligible to join U-M Online.
