Once you enter your my_profile user name, you will be asked the challenge question you selected when setting up your account. Answer the challenge question and you'll get your password immediately.
If you have any difficulty creating your my_profile account please send an email to ProfileAdmin@AlpineClubofCanada.ca include your name, membership number, and postal code with your email.
