2 React project communicate each other especially in authentication

JavaScript
1

Hello,

My application using React JS. I plan this

  1. React project A is a Login Page, Landing Page ( Display the Module like Talent Management, Recruitment, Rewards and so on )
  2. React project B is Talent Management
  3. React project C is Recruitment

My question is,

  1. User key in Username & Password in React project A
  2. The authentication process is within the React project A
  3. Is it possible user only click on Talent Management Module in Landing Page and the page will redirect into React project B without re-authentication ?

The React project B authentication is based on value from React project A to React project B. There is no need to re-login to enter the Talent Management module

I plan to separate the project because I want to divide the work and easy to maintain

Please help me to understand and my React design is accurate and proven
