Using Two-Factor Authentication to login to Vultr Control Panel

Last Updated: Tue, Mar 31, 2020
FAQ Security

Introduction

Two Factor Authentication, or 2FA, is a technique that adds a layer of security by requiring an additional authentication step to log in. For strong security, Vultr recommends:

  • Use a strong password. We have a free strong password generator available for your use.
  • Do not share your login information with any third party individual.
  • Use Two Factor Authentication for all users.

Vultr supports Two-Factor Authentication (2FA) using Google Authenticator and other compatible authenticator apps. Vultr also supports Yubikey and one-time-use emergency backup codes.

Usage Notes

  1. 2FA does not affect API Calls.
  2. 2FA does not change server login credentials.
  3. 2FA can be enabled on a per-user basis and does not affect the entire account.

Google Authenticator and Compatible Apps

Vultr supports 2FA with Google Authenticator and other Time-based One-time Password (TOTP) apps. Many apps are compatible with Google Authenticator. The Vultr portal refers to time-based codes as Google Auth, although you can use any compatible app, including:

To Enable 2FA via Google Authenticator

  5. Click the Add icon.
  6. The next page displays a QR code. Scan the QR code with the Google Authenticator app or the Chrome extension.
