WAC are actually not required anymore, although it is still avalable.
CRA My Account is accessible now via a system called "Secure Key Concierge", where the CRA redirects your login to your bank. As long as you have an account with one of the "Big 6", you can log into your online banking, after which the CRA federates with the bank and checks that your SIN and DOB at the bank is the same as the SIN and DOB you entered at the site, and if so they let you in.
IMO it is a much more convenient way to authenticate in a way that covers likely 90%+ of the Canadian population.
