Antwort auf Sicherheitsfrage bei Login abfragen

Sogma · 27. November 2020

Tag,

hier ein Guide wie man beim Client Login die Antwort auf die Sicherheitsfrage mit abprüfen kann.

Die Antwort auf die Sicherheitsfrage wird bei den meisten wohl in der Account Tabelle in der Spalte answer1 gespeichert sein.

In meinem Falle wird die Antwort bei der Registration auf der Website als Pflichtfeld abgefragt und dann als md5 hash in der Datenbank abgelegt.

Warum sollte man dies beim Login mit abfragen
