Um dos tópicos mais solicitados entre os assinantes do meu canal Dimka Reaktivny é autenticação e autorização no aplicativo React Native. Portanto, decidi abordar esse problema com um longrid separado e, antes de começarmos a codificar, é necessário lidar com a definição de autenticação / autorização.
Autenticação
trata-se de uma verificação da correspondência do sujeito e de quem ele está tentando se passar com a ajuda de algumas informações exclusivas (impressões digitais, cor da íris, voz etc.), no caso mais simples - com a ajuda do correio e da senha.
Conecte-se
é uma verificação e determinação da autoridade para executar determinadas ações de acordo com a autenticação executada anteriormente
No final deste artigo, criaremos este aplicativo móvel:
A autenticação é parte integrante de quase qualquer aplicativo. Saber quem é o usuário, o identificador exclusivo do usuário, quais permissões ele possui e se está logado, permite que o aplicativo exiba as visualizações corretas e retorne os dados corretos para o usuário conectado no momento.

- Amplify :
Data is stored unencrypted when using standard storage adapters (localStorage in the browser and AsyncStorage on React Native). Amplify gives you the option to use your own storage object to persist data. With this, you could write a thin wrapper around libraries like:
