IMAP Login using SecureString Credentials

Demonstrates the Chilkat Imap.LoginSecure method, which authenticates a connected session using SecureString credentials. The first argument is the login name and the second is the password. This is the secure-string counterpart of Login; the mechanism is chosen by the AuthMethod property.

Background: A SecureString keeps the credential encrypted in memory and helps avoid leaving plaintext copies lying around in the process, which is why the password should come from an interactive prompt, an environment variable, or a secrets vault — never a hard-coded literal. For XOAUTH2, pass the login name in the first argument and the raw access token (without a Bearer prefix) in the second.
