Login#

You can log in to the web application via a browser at https://smsdirect.telekom.sk. After verifying login credentials, the user is prompted to enter a verification code received via the selected two-factor authentication method (the default method is SMS). On first login, the user will be prompted to change their password.

Two-Factor Authentication#

Two-factor authentication (2FA) is a security mechanism that increases account protection by requiring identity verification using two independent factors during login. Typically, this is a combination of:

  • Something the user knows — e.g. password, PIN, etc.
    and
  • Something the user has (receives) — e.g. a code sent via SMS, email, or generated by an authenticator app

The OmniChannel web application supports 3 two-factor authentication methods:

  1. SMS
  2. Email
  3. TOTP

What Is TOTP?#

TOTP (Time-based One-Time Password), also known as a time-limited one-time password, is a form of two-factor authentication that uses one-time passwords generated based on the current time and a shared secret key between the user and the authentication server.

How TOTP works:

  1. During 2FA activation, the user receives a unique secret key, usually provided in the form of a QR code.
  2. The user saves this key in an authenticator app.
  3. The app then generates one-time access codes at regular intervals (typically every 30 seconds) based on the current system time and the stored secret key.
  4. During login, the user enters the current code from the app, which the server compares with its own calculated value. If they match, authentication succeeds.

Advantages of TOTP:

  1. Independence from internet connectivity — codes are generated locally without requiring network access.
  2. Increased security — one-time codes have a short lifespan, minimizing misuse risk.
  3. Standardization — TOTP is defined by RFC 6238, ensuring compatibility across implementations.

How to Use 2FA with TOTP#

  1. Install an authenticator app on your mobile device.
  2. Open your profile by clicking Account → Profile.
  3. In the Account tab, select Use TOTP as the two-factor authentication method and click Click to generate a new TOTP key.
  4. A screen with a QR code will appear. Open your authenticator app and scan the QR code.
  5. After scanning, your OmniChannel account will be added to the authenticator app.
  6. Enter the 6-digit numeric code associated with your OmniChannel account from the authenticator app into the Verification code field and click Confirm.
    • The Confirm button must be clicked before the code expires.
    • If the time limit expires, enter a new code.
  7. Click Save in the upper-right corner.
  8. On subsequent logins, you will be prompted to enter a 6-digit numeric code displayed for your OmniChannel account in the selected authenticator app.

Multiple Users Accessing a Single Account#

There are two ways to allow multiple users to access a single account:

  1. Create an alias for a new user (recommended).
  2. Share login credentials using TOTP two-factor authentication
    • When setting up TOTP-based 2FA, in step 4, scan the QR code with all devices that should be allowed to authenticate.
    • In step 6, use the code from any device, as the codes should be identical across all devices.
