Two-factor authentication is used for security and validation purposes.
Two-factor authentication provides a second level of security for your Ryerson account. In addition to your password, a time-limited code is required to log in. That way, even if someone steals your password, they may be prevented from hijacking your account when it’s protected by two-factor.
Codes are generated by devices you have with you. The device can be a mobile phone, a universal second factor (U2F) security key or a one-time verification (OTV) code generator.
