how to enter username and password ?

[s4miii]

Thanks for your beautiful job!
actually I need to enter username and password with your theme because I'm part of an Active directory system and I have bunch of usernames and passwords, for example sometime is like this user01@companyA.com and sometime like this user02@companyB.com
in some themes there is a button called other and you can enter both of them (user and password)
any solution ?
Thnx in advance
