Problemas com Tomcat embutido no NetBeans

Front-end
#1

Por que, meu Tomcat pede login e senha quando rodo a aplicação, e quando eu digito a senha ele diz que estar inválida?

alguem pode me dizer o que significa essa mensagem:

basta ler a mensagem
vc precisa irno arquivo user e setar um password para manager (se ja nao houver), se houver, basta ir no server manager e diggitar o user e password corretos.
