Implementing python I generated a one time password and berified them using a secret key.This can be used for a secure login.The random key can be set randomly . Using a counter based otp , 'hotp' .
we give indexes to the code sent for verification. Using this we can assign a number of values .
Using the python liblary qrcode we are able to generate a qrcode which can be used in the login process.
