JSON Web Tokens (JWTs) are quite common in the OAuth and OpenID Connect world. We’re so used to them that we often don’t pay much attention to how they’re actually used. The general opinion is that they’re good for being used as ID tokens or access tokens and that they’re secure — as the tokens are usually signed or even encrypted.
Vantagens do JWT
- Segurança: Assinado digitalmente, garantindo integridade e autenticidade do token.
- Autenticação Stateless: Não requer armazenamento de sessões no servidor, facilitando a escalabilidade.
- Compactação e Portabilidade: Tokens pequenos, em formato Base64, fáceis de transportar em cabeçalhos HTTP, cookies ou URLs.
- Flexibilidade com Claims: Permite armazenar informações úteis (como
user_id,roles, etc.) no payload.
JSON Web Tokens (JWTs) are important because they provide a secure way to authenticate users and share information. They are a standard tool for modern web applications.
