Security Benefits

[PawanVerma1]

To enhance security, I recommend using String OTP (STROTP) instead of traditional numeric OTPs.

Why Choose String OTP?

• More Secure – Harder to guess than numeric OTPs.
• Increased Complexity – Reduces the risk of brute-force attacks.
• Customizable – Can be tailored for different security needs (e.g., 6-character alphanumeric OTPs).

Implementing STROTP strengthens authentication and ensures better protection against unauthorized access.
My function is

function strotp()
{
$time=time();
return strtoupper(substr(md5($time), 0,6));
}
echo strotp();
