Installing with existing Emby installation. Password incorrect

[DaveDick00]

I'm trying to use Jellyfin with an existing installation of Emby.  I saw that Emby/JF both use the same default ports, I shut down Emby prior to installing JF.  
On the initial config screen for JF, I entered in the admin name/password, but when it came time to login, it said the password was incorrect (used the same admin name I have on Emby, but used a different password).

Is there anything special that I need to do ?  I did not try using my Emby password since I assume that Emby and Jellyfin config files are in different folders?

The install directories should be in entirely different locations. If you need to do the initial account setup you can go into system.xml and re-enable the setup wizard.

Stop Jellyfin.

Edit /etc/jellyfin/system.xml

<IsStartupWizardCompleted>true</IsStartupWizardCompleted>

Change to false. Start jellyfin.
