It's really not that hard to get your Wellesley password.
Go to the "Alumnae Password Reset" screen. (It's an odd name if you never had a password, but that's what it's called.)
Fill in the blanks and click Confirm. You should soon get email with a temporary password.
The password will go to your email address on file at the college. If it has been a while since you updated your contact information, they may not have your current (or any) email address. If you do not receive the temporary password email, or you have trouble resetting your password using the link to the Alumnae Password Reset screen, check in with the Wellesley College Help Desk at 781.283.7777 or firstname.lastname@example.org. They are open Monday through Friday from 8:30 am to 4:30 pm Eastern time.
