The Member Self-Service Portal (MSS) is a portal that allows members to revise their email, create a new Personal Identification Number (PIN), and update their preferred method for receiving communications such as email or mail. Members also have access to various printable forms and will use Okta to log in and authenticate to MSS. Set up your Okta account with a personal email only, and remember that MSS cannot be accessed through a state computer.

• Set up your Okta account with a personal email only. Do not use a work email.
• MSS cannot be accessed through a work computer issued by the state of Montana.
• You must first contact MPERA to get MSS access and receive your Person ID. The toll-free number for the MPERA Member Call Center is 877-275-7372, or in Helena, 406-444-3154.
