Escolher um fornecedor de autenticação do Microsoft Graph com base no cenário
Artigo
Os fornecedores de autenticação implementam o código necessário para adquirir um token com a Biblioteca de Autenticação da Microsoft (MSAL), processam alguns potenciais erros para casos como consentimento incremental, palavras-passe expiradas e acesso condicional e, em seguida, definem o cabeçalho de autorização do pedido HTTP. A tabela seguinte lista os fornecedores que correspondem aos cenários de diferentes tipos de aplicações.
Os fragmentos de código seguintes foram escritos com as versões mais recentes dos respetivos SDKs. Se encontrar erros de compilador com estes fragmentos, certifique-se de que tem as versões mais recentes. As seguintes bibliotecas de Identidade do Azure fornecem os fornecedores de autenticação utilizados:
Os programadores de .NET têm de adicionar o pacote Azure.Identity .
Os programadores de TypeScript e JavaScript têm de adicionar a biblioteca de @azure/identidade .

O fornecedor de nome de utilizador/palavra-passe permite que uma aplicação inicie sessão num utilizador com o respetivo nome de utilizador e palavra-passe.
Observação
A Microsoft recomenda que utilize o fluxo de autenticação mais seguro disponível. O fluxo de autenticação descrito neste procedimento requer um grau muito elevado de confiança na aplicação e acarreta riscos que não estão presentes noutros fluxos. Só deve utilizar este fluxo quando outros fluxos mais seguros, como identidades geridas, não forem viáveis. Para obter mais informações, veja plataforma de identidade da Microsoft e a credencial de palavra-passe do proprietário do recurso OAuth 2.0.
