OTP Full Form

What is the Full form of OTP?

The full form of OTP is One-time password. One-time password (OTP) systems offer a way to access a network or service using a special password that, as the name implies, can only be used once.

Single-Factor Authentication (SFA)

The standard security procedure, single-factor authentication, requires a username and password before providing access to the user.

OTP and Smart Cards

Advanced hardware tokens compute one-time passwords using smart cards with microprocessors.

Strong authentication may be achieved using smart cards thanks to their data storage capacity, processing power, portability, and user-friendliness.

They produce a different, non-reusable password for each authentication event, save user information, and don't send sensitive information over the network, making them intrinsically more secure than other OTP tokens.

Grid Cards

One-time passwords can be generated using straightforward techniques like grid cards and transaction number lists.

Although these techniques involve little up-front investment, they are slow, challenging to maintain, simple to duplicate, and shared, and they need the users to keep track of their position in the list of passwords.

Security Tokens

An OTP token, a piece of hardware that can create one-time passwords is a more practical option for users.PIN protection is available on some of these devices, adding an extra layer of security.An authentication server verifies the logon request when the user inputs the one-time password together with additional identity credentials (usually the user name and password).

Although this is a tried-and-true option for commercial apps, it may be pricey for consumer applications due to setup costs.Users need a distinct token for each Web site or network they use since the token must utilise the same technique as the server and is therefore required for each server login.

Strong OTP Authentication with Public Key Infrastructure

Additional authentication features, such as PKI or Public Key Infrastructure certifications, can be added to smart cards.The smart card device may deliver essential PKI services, such as encryption, digital signature, and private key generation and storage, when utilised for PKI applications.Both the JavaTM and Microsoft.NET platforms are supported by Thales smart cards for OTP strong authentication.End users can choose from a variety of form factors and connectivity options to choose the device that best suits their needs for network access.The same Strong Authentication Server and same set of management tools are supported by all Thales OTP devices.

Conclusion

To enable a single login session or transaction, a one-time PIN code is a code that is automatically created and sent, typically to a mobile device.
