the username or password is provided by kodekloud is unable to login.
and i am not able to complete task
Did you look in the jenkins log to get the “initial administration password” before you did this? I’m not sure how you got to that screen, but for me, I got the “unlock jenkings screen”, which is different. Please tell me what you did to get to this point.
i am put initial administration password and a signup page is open, it required email so i go through login as admin but i check the the task its give error so i logout and try to login but gives this type of error i mentioned in previous screenshot
I don’t think you can rely on email working in the lab 
If you just set the passwords after activating the admin account with the initial password, you can successfully set the admin user and its password.
but i click on admin account, its not ask anything like set username or password its directly login to admin account, and then i check my task give error, why?
The initial screen you get is the “unlocking screen”. After that you’re offered the opportunity to install plugins. After that, there’s a form where you can set the user name of the admin + the admin password. At least, that’s what I saw earlier today when I tried Q6.
i signup with email then its work.
thank you
