How to Generated a random username number

[Riskov]

Ok All I want is a "Username Pass dialog"
username will be the MAC adress
password will be the mac adress + smth

How will the program work - the user will email me the mac adress to generate him the pass and I'll give 'em

[Riskov]

Ok I've found a lot of info
And I have 3 users with 3 passowrds that work

user1 userpas1
user2 userpas2
user3 userpas3

after instalation it's showing the mac adres and other numbers


What i want is the username to be the mac adress or some numbers that are unique for every computer and the password to be a mathematical function of the username

Example:



here the username must be 72585494726656 and the password to be 72585494726656+123=72585494726879 (123 is just a number I chose)
