Apple id and password not working,what will i do?

See: If you forgot your Apple ID  https://support.apple.com/en-us/HT201354 and

 If you forgot your Apple ID password https://support.apple.com/en-us/HT201487

You also can use Having trouble signing in/iForgot https://iforgot.apple.com/password/verify/appleid 

And you will need to see If you forgot the answers to your Apple ID security questions https://support.apple.com/en-us/HT201485

Before trying to answer your security questions is very important that you think about your questions, including your birth date, and their answers carefully and try to recall all details you can. If you don't answer them correctly enough, then you easily can lose control of your account.

I think your account is going to end up being disabled if you pursue matters as above. See If your Apple ID is locked or disabled https://support.apple.com/en-us/HT204106 

And, thus, you will need to try to recover your account. See Recover your Apple ID when you can’t reset your password https://support.apple.com/en-us/HT204921.

Device or computer? Where are you trying to sign in when they won't work? What happens when you try? Error message(s)? More information would help.
