'Unable to log in to Jenkins after installation

I installed Jenkins on my mac via brew.

As instructed, I have started the service, and navigated to:

http://localhost:8080

I expected to see this:

I am being asked for my username and password.

Instead, I seeing:

The user name I am using is admin

The password I am using is the password that was provided as part of the installation process.

This is not working. I am getting an Invalid username or password message.

Can someone please help me? I have installed / reinstalled etc.

Thank you, Sean
