Multi Factor Authentication with Time-based One-Time Password (TOTP)๏ƒ

Two-factor authentication is an additional layer of security designed to prevent unauthorized access to your account and protect access to the Virtual Machines and other data you store with the ITS Private Cloud.

The VSS Command Line interface offers the following commands to manage MFA settings in your account:

vss-cli account --no-load set mfa --help

Usage: vss-cli account set mfa [OPTIONS] COMMAND [ARGS]...

  Set account MFA settings.

Options:
  --help  Show this message and exit.

Commands:
  get-token  Request TOTP token.
  mk         Enable MFA with Time-based One-Time Password.
  rm         Disable existing MFA setup.
  verify     Verify existing MFA setup.

Enable๏ƒ

MFA is enabled by adding the mk sub-command and providing the method to generate or get the TOTP codes. Currently, the ITS Private Cloud supports EMAIL, AUTHENTICATOR or SMS.

vss-cli account --no-load set mfa mk --help

Usage: vss-cli account set mfa mk [OPTIONS] {EMAIL|AUTHENTICATOR|SMS}

  Enable MFA with Time-based One-Time Password.

Options:
  --phone TEXT  phone number to receive SMS
  --help        Show this message and exit.

For instance, enabling MFA on a given account using AUTHENTICATOR would look like the following command:

vss-cli account --no-load set mfa mk AUTHENTICATOR
