I am pretty sure I already know the answer to this ?, but I logged into my zimbra account this morning no problems. 12 hours later (tonight) I'm getting pop-up to re-authenticate account, but when I attempt to do so, it tells me my password may have changed and to check edit screen:

Password may have changed. Please go to edit screen of Account Setup to revalidate settings.

Where do I go to reset, other than to wait until a.m when sysadmin gets in.

Thanks, T
