If working with files that are ":" field delimited:

Code:
 
pwds file (pwd:replace pwd):
s/1zg6/2RWAUY,2/lR:@#xyyyy$@#!$@#
JQy74TuvHyqMo:@#$@#!xxxxx$@#
32oVGmESDPBLk:@#$@234234wa#!$@#
VkrDf0FVYbg7.,2/cW:@#$sss@#!$@#
hWTRS2IF9EOQc,2/mW:@#$@aaaa#!$@#
OrfQo.EYJo9q6:@#$35345@#!$@#
2oK927ArLTgnY,B.mW:@#$@23234#!$@#

somefile:
Code:
user:s/1zg6/2RWAUY,2/lR:user:::::
user:JQy74TuvHyqMo:user:::::
user:32oVGmESDPBLk:1162:user:::::
user:VkrDf0FVYbg7.,2/cW:user:::::
user:hWTRS2IF9EOQc,2/mW:user:::::
user:OrfQo.EYJo9q6:user:::::
user:2oK927ArLTgnY,B.mW:user:::::


using awk:
Code:
 
awk -F: '
NR==FNR {pw[$1]=$2; next;}
{ FS=":";
  for (i=1; i<=NF; i++) {
    if (length(pw[$i])>0) $i=pw[$i];
  }
  print;
}
' OFS=: pwds somefile

output:
Code:
 
user:@#xyyyy$@#!$@#:user:::::
user:@#$@#!xxxxx$@#:user:::::
user:@#$@234234wa#!$@#:1162:user:::::
