Multi-factor authentication to access My Service Canada Account

Multi-factor authentication is an improved security measure. It helps protect your personal information. We face ongoing and persistent online threats. This new security step helps prevent unauthorized access to your My Service Canada Account (MSCA).

Registration is mandatory for all users.

How to register

To register, you’ll have to:

  • sign in to your MSCA account, or register for an account if you’re a new user
  • answer the security questions that appear on the screen (GCKey users only)
  • choose 1 of the following security options on the multi-factor authentication screen:

Text message (SMS)

Provide your cell phone number to receive a security code by text message (SMS). You can provide a local and international phone number. Enter the code you received on the next screen to confirm your identity.

Voice message

Provide your local or international phone number (cell phone or landline) to receive a security code by voice message. Enter the code you received on the next screen to confirm your identity.

After you register

Once your identity is confirmed, you will have access to MSCA. You’ll need to enter a security code to confirm your identity each time you sign in to MSCA.

You can reset your multi-factor authentication security option if you:

  • lost your smartphone/tablet or it got stolen
  • changed your phone number
  • want to use another multi-factor authentication option


We don’t charge for these services. Your service provider may charge standard message and data rates. Contact them for questions about your plan and costs.

If your MSCA is locked due to the security code, please contact our Registration and Authentication Help Desk at 1-866-279-5238. We can help you from 8:30 am to 4:30 pm local time, Monday to Friday (closed on civic holidays).
