Private member access
Your MCHS member space.
Keep your membership contact preferences together while MCHS confirms applications, dues, and benefits separately.
Sign in to continue.
Use a Microsoft or GitHub account you control. This creates a private MCHS member-portal record only; it does not grant staff access, approve a membership, or collect payment.
Do not use a shared staff account. MCHS never receives your Microsoft or GitHub password.

My membership contact preferences
If you received an application reference, save it here so staff can match your private profile manually. Saving it does not approve membership.
Pay membership dues
Use an option below only after applying or renewing so MCHS can match the payment to your membership. Confirm that the recipient name is Mercer County Historical Society. The website never asks for or stores your card or bank details.
Password and sign-in help
The current secure pilot uses Microsoft or GitHub authentication. Reset the password with the provider used to sign in; MCHS never receives that password or recovery code.
Email-only MCHS sign-in requires an approved identity and email-delivery service before it can replace these providers.
