I do not wish to use Google Authenticator or Authy app that generates 2 step verification (2FA) codes on my iOS/Android phone. Is there any way I can produce 2FA codes from Linux command line for popular sites such as Gmail, Twitter, Facebook, Amazon and more?

The mobile apps generate secure 2 step verification codes to protect your online accounts from hackers. You get an additional layer of security. In addition to your password, you need to input 2FA codes for each login. This page explains how to use oathtool OTPs (one-time password) on Linux to secure your Gmail and other online accounts. Instead of waiting for text messages, get verification codes for free from the oathtool Linux command.
