Thomson Reuters strongly recommends that you use multi-factor authentication to provide the highest level of security for your firm and client data. 

What is multi-factor authentication?

Multi-factor authentication adds an additional layer of security that helps protect your firm's confidential data. Many of your online accounts or software applications are currently protected by a login and password. That password is the single factor in the authentication process — the way that those applications or services confirm your identity. 

Multi-factor authentication adds at least one more layer of identity verification to that process so your protection against hacking and fraud attempts is stronger and more secure than a simple password. That additional layer can take many forms, such as a physical ID card, a digital confirmation code, or even your fingerprint. You're using multi-factor authentication every time you pay a transaction using a debit card or withdraw cash from an ATM: your debit card is one factor and your PIN is another.

How does it work?

Thomson Reuters applications provide multi-factor authentication through the Thomson Reuters Authenticator mobile app. After installing the mobile app on your smartphone and pairing that device with your application login credentials, you'll use the Authenticator to confirm your identity when you log in to your CS Professional Suite applications. You do so via a notification that is sent to the Authenticator mobile app, which you can quickly approve on your mobile device. 

Implementing multi-factor authentication in your firm

By default, multi-factor authentication is an optional feature that individual users can opt into by enabling it for their own accounts. If desired, firm administrators can enable a setting that requires that all staff members log in with multi-factor authentication.
