Two-Factor Auth Account

In this article


Use this account type to connect Binary Snaps with data sources that use Two-Factor Auth accounts. This account supports two factor authentication (2FA) for Security File Transfer Protocol (SFTP) to access SFTP. It uses two separate security layers of verification to grant access that include the Basic Auth (username/password) and the SSH Key (username/private key) methods.


  • Target FTP should be enabled with Two-Factor authentication.
  • Valid username/password and SSH key with passphrase.

Account Encryption

Standard Encryption

If you are using Standard Encryption, follow the High sensitivity settings under Enhanced Encryption.

Enhanced Encryption

  • High: Key passphrase
  • Medium + High: Username, Key passphrase
  • Low + Medium + High: Username, Private key, Key passphrase

Generating SSH Key Using PuTTY Key Generator

You can download the PuTTYgen application for Windows using this link.

  1. Open the PuTTYgen application.

  2. Choose SSH-1 (RSA) key type under Parameters.
  3. Enter the required value in the Number of bits in a generate key field. (Default: 2048)
  4. Click Generate that is adjacent to Generate a public/private key pair under Actions.

    The PuTTY Key Generator uses mouse movements to generate a unique secure key. Move the mouse around till the progress bar fills up completely.

    The utility generates the public and private keys.

  5. Provide values in the Key comment and Key passphrase fields as required.
  6. Click Save public key and Save private key to save the private and public key (PPK) files to a secure and private location.
  7. Send the Public Key to the SFTP host.
  8. Store the keys and passphrase into the password/key vault.

The PuTTY Key Generator uses the PPK format for keys. If your SFTP client requires a standard OpenSSH key format, export the key by using Export OpenSSH Key on the Conversions menu.
