I would like to create a website login page which makes it secure for small scale website owners to use and protect from hacking of their admin password, to accomplish this instead of normal login by "User name" and "Password", I would like to do the following:
- I will use a user name for the particular user.
- Instead of password I need to create a Generate Button which would generate an OTP (One Time Password) every time the user tries to login to his website. Once the OTP has been generated I need a free service that could sent that generated OTP to a mobile phone via SMS.
- If there is a network problem in mobile I need to send those OTP to a e-mail id saved during the registration period
Is there any free service that could provide my need to send an OTP via SMS?
