OpManager Application Manager plugin asking to reauthenticate

OpManager Application Manager plugin asking to reauthenticate

I've installed a trial version of OpManager v11.5 along with AppManager plugin. the problem is that when I try to browse to OpManager parts related to AppManager plugin, it asks me for username and password.
I login with the below credentials:
user: admin
pass: admin@opm
Is there any way to bypass the authentication for this plugin?
