If you receive this error message, it almost always means that you have used your MCC password and not your library password in the form below. 
You did not know that you needed a library password? You do to get off-campus access to most of our resources. The good news is that your library password is, by default, your birthdate in the MMDDYYYY form with no slashes, spaces, or punctuation. Here is the link to the explanation of off-campus access and library passwords. (http://libguides.middlesex.mass.edu/offcampus)
If you still cannot connect, please contact the library via email (mcclibrary@middlesex.edu) or by text @ 978-241-7884.
