In computer security, shibboleth refers to digital credentials (such as passwords) or physical credentials (such as RFID cards or fingerprint scans) used to protect computer access. Interestingly, the word "shibboleth" itself was once used as shibboleth: in the Old Testament, Gileadites pronounced it as shibboleth, which distinguished them from Ephraimites who pronounced it as sibboleth.
1) composure or coolness as shown in danger or under trying circumstances.
If you know French, then you know that sang is blood, froid is cold, so sangfroid literally means cold-blooded. Sometimes spelled with a hyphen, as in sang-froid.
