Cause:
Password file is missing OR not synched between Primary and Standby with same sys password

SOLUTION:
First connect your Primary Database and change the sys password if you dont know existing password.

sqlplus / as sysdba
alter user sys identified by Oracle123123;

Linux/Unix:
$ORACLE_HOME/bin/orapwd file=$ORACLE_HOME/dbs/pwdPROD password=YourSysPassword entries=5 force=y

MS Windows:
%ORACLE_HOME%\bin\orapwd file=%ORACLE_HOME%\database\pwdEBSUAT.ora password=Oracle123123$ entries=5 force=y

NOTE:
In Windows Platform Make sure the Password file has the .ora extension since i faced errors without extention.
After the password is generated , Transfer to Standby Database respectively and better rename password to Standby Unique Name too respectively.
