Logging in with your barcode
The simplest way to log in is using your MAC ID if you are a currently registered McMaster faculty, staff or student.
If this is your first time signing on to your library account:
- Enter the 14-digit barcode on your McMaster identification card or Working @ McMaster card
- Leave the PIN field blank
- Hit Submit
- Set and confirm a new 4-digit PIN
You can change your PIN when logged in to your account. PINs must be numeric.
