More advanced hardware tokens use microprocessor-based smart cards to calculate one-time passwords. The user enters the one-time password with other identity credentials (typically user name and password), and an authentication server validates the logon request.Īlthough this is a proven solution for enterprise applications, the deployment cost can make the solution expensive for consumer applications.īecause the token must be using the same method as the server, a separate token is required for each server login, so users need a different token for each Web site or network they use. Some of these devices are PIN-protected, offering an additional level of security. These methods offer low investment costs but are slow, difficult to maintain, easy to replicate and share, and require the users to keep track of where they are in the list of passwords.Ī more convenient way for users is to use an OTP token, a hardware device capable of generating one-time passwords. Simple methods such as transaction number lists and grid cards can provide a set of one-time passwords. One-time passwords can be generated in several ways, each with security, convenience, cost, and accuracy trade-offs. Time-based One-Time Password ( TOTP) changes after a set period, such as 60 seconds. This feature adds extra protection and makes it more challenging to access unauthorized information, networks, or online accounts. Robust authentication systems address the limitations of static passwords by incorporating an additional security credential, such as a temporary one-time password (OTP), to protect network access and end-users' digital identities. OTP and TOTP vs static passwordĪlthough this authentication method is convenient, it is not secure because online identity theft – using phishing, keyboard logging, man-in-the-middle attacks, and other practices – is increasing worldwide. Today most enterprise networks, e-commerce sites, and online communities require only a username and static password for login and access to personal and sensitive data. One-time passwords (aka One-time passcodes) are a form of strong authentication, providing much better protection to eBanking, corporate networks, and other systems containing sensitive data.Īuthentication answers the question: " Are you indeed Mr or Mrs /en/markets/digital-identity-and-security/banking-payment/digital-banking/passkeys-for-financial-institutions X?" Typically the user's login name stays the same, and the one-time password changes with each login. The OTP feature prevents some forms of identity theft by making sure that a captured username/password pair cannot be used a second time. If "qwerty" is always your password, it's time to change. The static password is the most common authentication method and the least secure. One-time password (OTP) systems provide a mechanism for logging on to a network or service using a unique password that can only be used onc e, as the name suggests.
