What is the full form of OTP

One-Time Password (OTP) tokens, OATH-compliant authentication tokens, keypads, and cards

Our OATH-compliant one-time password tokens offer simple, secure and cost-effective options for implementing stricter user access control in your company.

OTP tokens are one of the easiest options for secure authentication and are often used by organizations that want to make their login processes more secure, quickly and effectively.

OTP types

OTP tokens are available in two versions: event-based (HOTP) and time-based (TOTP). Event-based OTP tokens generate a new code at the push of a button, which is valid until it is used by the application. Time-based OTP tokens generate codes that are only valid for a certain period (e.g. 30 or 60 seconds). After this period has expired, a new code must be generated.

You will also find keypad tokens that offer PIN-protected OTP and challenge-response functions. In challenge-response mode, the user must first enter a challenge code (which is displayed by the application, for example) and the token generates a response code that the user enters into the application. These tokens can be used for challenge-response procedures, the generation of electronic signatures and the approval of transactions.

OTP authentication server

Provide OTP tokens with our Identity and Access Management System (IAM) and give your organization full control over the issuance and reclamation of tokens to users. Our SmartSign solution has IAM functions as well as a multi-factor authentication server and a token management system.
