Para gerar novas chaves offline é recomendado usar steem-paperwallet ou se você não se importar com segurança hivetasks
E para criar a conta você deve ter uma conta propria e pode usar meu site ou account creator do hivetasks
A vantagem de criar uma conta usando chaves publicas é que você pode criar uma contas para amigos ou desconhecido sem precisa saber das senhas deles, outra vantagem é ter as chaves privadas totalmente offline, pelo menos a chave master e owner.
Codigo do site que criei html e javascript, você pode copiar o codigo e salvar como index.html que funciona localmente;
