Question about Az powershell authentication contexts persistence

[aml276]

According to the documentation, when I authenticate using the Connect-AzAccount command, it stores the authentication context in the CurrentUser scope to be used between multiple powershell sessions. How long is the authentication context valid, and does it need to be refreshed periodically?

I am building an app that needs to authenticate with Az Powershell across multiple Powershell processes, and I need to know if I can authenticate once and the context will be valid indefinitely until the user is logged out.

If you login with an application, you'll receive an access token which expires in one hour.
But If you login with application and password or application and certificate, we are going to cache your credentials and will acquire the token for you automatically. (Please note don't change the certificate file path)
If you login with application and federated token, you have to run Connect-AzAccount once an hour.
