Answer 1

I think you should to try this:

username ="fay"
password ="321"
user_name = input("What is your username?:")
while user_name!=username:
    user_name=input("please re-enter username:")

passWord= input("Please enter your password:")

while passWord != password:
    passWord=input("please re-enter password:")  
 
print("welcome!")
