Change password of application without using database in c#

If you want to do that you need to have a second connection. 1 to your database, another one to a textfile were you can store username and password.It needs to be stored somewhere otherwise when you close the application the data will be gone. After that you need to change your login method so it would first take a look at the textfile wich contains the username and password, but if it can't find any matching result it should check your database. I olso agree with the person who answered above me :)

You can, but how are you going to update the password value in the database? 

 

Because, the next time you connect to the database for login purposes, you are going to get the same password again. Which is why, you are not going to get any benefit from this update.
