How to send a random generated number along with email and password while logging in with laravel 5.6

I want to send a random generated number along with password and email field when the user is logging and attach that number where laravel is grabbing the user password (i want to attach the random number to the password that laravel grabs from the user table then check it against the password that the user entered in the login field) However i am not able to send the random number from the login blade in a hidden field. Please help
