Authentication Progress

If you do not specify username on Login dialog, WinSCP will prompt you once it needs it for authentication.

If you are using password authentication, you can enter your password directly on Login dialog. Otherwise WinSCP will prompt you once a server asks for it. You will be prompted again, if you enter invalid password. Also note that most of the servers will “prompt” for password when you use invalid username, not to allow attacker to learn if particular account exists.

You can opt to Remember password for the session to avoid getting prompted for password again when reconnecting or opening additional connection. You can also opt to remember the password for all sessions in preferences.

When authentication with stored password (if any) has failed before, the prompt will include Change stored password to this one check. Use it to overwrite stored password with new one.

If you are using public key authentication with encrypted private key you will be prompted to enter passphrase for your key.

During authentication against SSH server, the server can issue authentication banner. It can contain various information, generally regarding security and server usage. After reviewing the text, press Continue button to continue.

If you want to avoid seeing the banner each time you login, check Never show this banner again. It will make WinSCP ignore the same banner for the particular account and server the next time. However if the banner content changes you will see it again. Suppression of banners can be restricted by system administrator.

During authentication, the server may request you to change a password, particularly if your password has expired.

Enter your current password to Current password.

Enter your new password to New password and once again to Confirm new password.

Note that the server may use keyboard interactive method for change password request. Then the prompts will differ.
