Two Factor Authentication, also known as 2FA or multi-step verification, adds another layer of security, supplementing the username and password model with a code that only a specific user has access to (typically sent to something they have immediately to hand). This authentication method can be easily summed up as a combination of "something you have and something you know".
QCSD now allows staff and students to enable 2FA to further protect their accounts. If you are interested in turning on 2FA on your account you can follow the simple directions here:
