Watchouts

Reasons buyers look elsewhere

OTPLESS

  • Organizations that rely on traditional 2FA, hardware tokens, or OTP-based systems may find OTPLESS incompatible with their current workflows or compliance mandates that still require such methods.
  • Some businesses prefer solutions offering more granular control over authentication journeys, including customizable challenge-response flows or admin dashboards with advanced analytics and policy settings.
  • OTPLESS focuses heavily on contextual and behavioral authentication. In highly regulated industries, businesses may require additional hard-factor mechanisms such as smart cards or hardware tokens, which OTPLESS may not offer natively.
