Is changing my apple id can affect my current app?

Hi Good Morning,

I just want to know if i am going to change my Apple ID and Password do you think there will be some effect on my current apps? It happens that i can't remember my Password and i don't have any access to my email because i forgotten it all. Also the security questions i can't answer them correctly. I just can't update the application that needs to update because it is requesting for a password.

Thank you.
