With the introduction of new techniques of verifying a user like fingerprint scanning, face recognition, retinal scans, and puzzle solving; daily static passwords are being less protected and unwieldy for users to keep in mind. When the Internet first began, it was exhilarating to have a powerful and hard to detect password for your emails, but now these similar types of passwords can be simply detected and hacked into.
Increasing number of people are using online banking, making financial transactions, buying things online on their Smartphone, and keeping sensitive information on the Internet. Regular passwords are not very secure to defend users against malware and hacker attacks. So, One Time Password is the best method to defend users from fraud and malware attacks, particularly if combined with an out of band verification method.
One Time Password Services
Banking and financial organizations use OTPs to secure their user logins using an out of band verification method. How it works is that a user feeds their login information and their mobile phone is delivered with a one-time password from an external server. Once the user obtains the password on their mobile phone, they feeds it into the website they are attempting to get access to and access is permitted if the one time password is accurate. This is one of the best methods to verify a user because the password is delivered to a user's mobile phone. This is a type of authentication method that does not require a user to carry extra hardware or even install extra software on their cell phone to use which makes it more suitable than hardware tokens. It is also the best way to verify a user because most users keep their mobile phones always with them.
OTP or one time password can be generated for mobile phone supporting Java language and JAVA SMS API . It makes use of MD4 and MD5 hash algorithms. Google also uses one-time passwords and delivers to their users if a user is signing in from a different IP address than the one generally used if the user asks for this service. One time passwords are not just as safe as they used to be even though they are still broadly used, so when opting for the OTP services go with a reputed name. One time passwords are going to be the prospect of authentication, making user's sensitive data safe.
