General Questions

How to Register in the App?

To use the app, you need to install it, register, and log in using your perconal credentials.

Instructions are available in the step-by-step registration guide.

After registration, you can log in to the app again from an unlimited number of computers and mobile devices.

For Administrators: How User Registration Works
  1. First, a personal account is created on
    RTS
    (eXpress) and/or on
    ETS
    (branded ETS app). For the personal account, the user’s HUID, which identifies them in the system, and encryption keys are generated (these can be additionally secured with a personal password in the app settings).
  2. Next, the user can remain on
    RTS
    as a public user (only in eXpress and only via phone number) or link their personal account to a
    CTS
    /
    eCTS
    corporate account, becoming a corporate user (mandatory in an
    ETS
    app and in the eXpress Corporate app).
Corporate user authentication is supported through various methods — more details.

Where to Get an Account?
