Multi-Factor Authentication
Clavister Secure Access Gateway offers a multitude of different authentication methods, ranging from single factor authentication methods, such as username/password, Web-based token, to multi-factor authentication methods, such as the use of SMS token with one-time passwords.
The purpose of a one-time password (OTP) is to make it more difficult to gain unauthorized access to restricted resources. Traditionally static passwords can more easily be accessed by an unauthorized intruder given enough attempts and time. By constantly altering the password, as it is done with a one-time password, this risk can be greatly reduced.
Multi-factor authentication combines two or more factors to make it harder to illegally obtain a user's credentials. One factor is something that the user has, for example a mobile phone and something that the user knows, for example a pass phrase. By requiring both these factors when users are asked to authenticate themselves, a high level of security is achieved.
One-Time Password
The one-time password is generated by the Clavister Secure Access Gateway and distributed by Clavister Service Provisioning Network (CSPN) to the user's mobile phone as a flash SMS. The one-time password expires once it has been used or its scheduled lifecycle has expired.
The Clavister SMS One-Time Password Service offers a number of advantages over standard SMS delivery. Clavister can offer connectivity to more than 200 operators around the world and 99.5% of all SMS are delivered within seconds. Since one-time passwords are time-restricted, a timely delivery is of the essence.
