Two-factor authentication & sign-in security

How adaptive sign-in and trusted devices keep your account safe.

Kartadum uses adaptive sign-in: an extra security check appears on new or untrusted devices, while trusted devices reduce friction on later sign-ins.

  • Expect an additional verification step when signing in from a new device or location.
  • Keep your email secure — it's used for account recovery and security notifications.
