Playwright provides a way to reuse the signed-in state in the tests. That way you can log in only once and then skip the log in step for all of the tests.

Web apps use cookie-based or token-based authentication, where authenticated state is stored as cookies or in local storage. Playwright provides browserContext.storageState([options]) method that can be used to retrieve storage state from authenticated contexts and then create new contexts with pre-populated state.

Cookies and local storage state can be used across different browsers. They depend on your application's authentication model: some apps might require both cookies and local storage.
