O comércio eletrónico trouxe mudanças drásticas na forma como as transacções comerciais são conduzidas, levando os bancos e outras empresas a adotar sistemas de pagamento eletrónico. Não só oferece ao sector bancário e a outras empresas uma grande oportunidade, como também cria riscos e vulnerabilidades. O principal objetivo desta investigação foi abordar questões de segurança relacionadas com o mecanismo de autenticação baseado em palavras-passe em sÃtios Web de comércio eletrónico, como a quebra de palavras-passe. A investigação pretendia conceber um sistema que tivesse a capacidade de atenuar a adivinhação de palavras-passe e os ataques de força bruta, uma vez que as frases-passe permitem caracteres especiais como o espaço. Recomenda-se que as frases-chave sejam concebidas para serem seleccionadas pelo utilizador, uma vez que são mais fáceis de utilizar do que as palavras-passe geradas pelo sistema. Os utilizadores devem também ter muito cuidado ao escrever ou armazenar frases-chave.
