For customers that already have an Onvio sign-in, they will enter the same credentials they are using today.
For DT Client Portal customers, they will be prompted to upgrade theirs DT Client Portal accounts to new Thomson Reuters Accounts and set up two-factor authentication the first time they sign in after the update is available.
For DT FileCabinet and DT Practice customers, they will sign in using either their DT Client Portal staff account credentials (after upgrading them), or Onvio staff account credentials.
It is now required to set up two-factor authentication. This may be a new experience for some customers if MFA was not required in the past. Also note that the current MFA process will be changed as part of the Thomson Reuters Account upgrade.
