What is the Best practice of dynamic changing password for this scenario?

The scenario is:

There are three web apps using ASP.NET.

App1 checks the passwords of app2/app3 to authenticate the identity, and if app2/app3 is authenticated then app1 is allowed to receive information from App2 and App3.

And app1 has to change the passwords of app2/app3 every two hour for security reason.

Is it possible that there is a way to implement this scenario without app1 saving the passwords of app2/app3 for security reason?

Or is there any best practice for dynamic changing password scenario?
