Answer 2

If you're looking for a simple solution, saving the user name and password in user settings would work. However, this approach is not very secure at all because any other user with sufficient privileges on this machine could simply read the saved settings and steal your login details.

Answer 3

The simple solution suggested by Bus above with encryption on the password may have some value.

Answer 4

To persist user credentials easily and in a secure way you can write them to the application configuration file using the ConfigurationManager class, secure the password using the SecureString class and then encrypt it using tools in the Cryptography namespace.

Answer 5

Here's a class you can download and possibly use. It uses the windows Credential API and provides a dialog, much like the credential dialog in windows, that allows you to save credentials.

It was a proof of concept I did, but it was never need in a production application. So use at your own risk :)
