On my SDP 14.1 Build 14102 (installed onpremises on postgres) I just have a case of all 2 SDadmin accounts changed passwords

I managed to recover access with the know commands
But this is strange...
Also the tech passwords are expiring and the setting is to "never expires"
could this be a bug
or I have some security issue on my network?
Are there any logs for the IPs that changed these passwords on SDP?
