Change SSO administrator password - what to consider?

Hello all,

I need to change the SSO administrator@vsphere.local password on one of my environments running vSphere 5.5

Although I have not been able to find on the internet any issues produced because of it, I would like to know what i should consider prior to changing this. I mean, what might it break? for example: I have vCO which was integrated in first instance with vCenter using these credentials, will I need to reconfigure it?

Any info would be really appreciated
