Online identities today are driving world on both the horizons of a user, online and offline.
What we are online is now becoming part of our offline world, like registration done online for a contest is used in offline world.
Another best example is applying for a credit card online. While applying for a credit card a unique number is generated which is the centric point of all the paperwork and processes related to getting a credit card.
Often a random number generated online, becomes your identity which travels from online world to offline world accomplishing every work which requires identity.
This means online identities are very much important and their protection is must.
OTP login is one of the many ways which can help minimizing identity theft. It uses SMS as medium to authenticate a user.
It cannot be considered as a full-proof way because things can happen at user’s end which can bypass it.
How OTP login works?
As mentioned above, OTP login makes use of SMS as medium to authenticate a user. Whenever a user, who has opted for OTP login visits a site, they authenticate to website by inputting their registered mobile number instead of a username.
As soon as user submits the mobile number, a timer starts with reverse count.
In this time user receives a message with a temporary code which upon validating on website allows user to authenticate.
OTP received on mobile has an expiration limit and is unique, which makes it safe.
How OTP login helps securing Identities?
While authenticating to a site, otp is required for validation. If someone has that OTP code then it will be useless for them because of single session and timeout limit of an OTP.
So every time someone wants to authenticate to a site, they will require a new otp.
This is how identities can be safeguarded while authenticating.
