Bitwarden Authenticator

When it comes to securing your Linux console, passwords are often the first line of defense against unauthorized access. However, they can be easily compromised by sophisticated hackers. To add an extra layer of security, you can enable two-factor authentication (2FA) on your console, su, sudo, and SSH access. In this article, we will explore how to use Bitwarden Authenticator Key to implement TOTP (Time-Based One-Time Passwords) authentication.

What is TOTP?

In simple terms, TOTP is a 6-digit code that changes every n-number of seconds and is derived from a shared secret. This type of multi-factor authentication is widely used in apps like Google Authenticator and Authy to provide an additional layer of security. With TOTP, even if your password is compromised, the hacker will not be able to access your account without having access to the one-time code.

Getting Started with Bitwarden Authenticator Key

To get started with Bitwarden Authenticator Key, you need to generate a secret key and scan it using the Bitwarden app. You can do this by following these steps:

1. Log in to your Bitwarden account and navigate to the 'Settings' section.

2. Scroll down to the 'Two-Factor Authentication' section and click on 'Generate Secret Key'.

3. Scan the QR code or manually enter the secret key into your Bitwarden app.

Setting Up TOTP

Once you have generated the secret key, you can set up TOTP for your Linux console, su, sudo, and SSH access. Here are the steps:

1. Open your terminal and navigate to the directory where you want to store the TOTP file.

2. Use the `bitwarden` command to generate a TOTP file: `bitwarden totp -s `.

3. This will create a file called `totp.txt` that contains the verification code.

Using Bitwarden Authenticator Key with SSH

To use Bitwarden Authenticator Key with SSH, you need to add the secret key to your SSH configuration file. Here are the steps:

1. Open your SSH configuration file in a text editor: `sudo nano /etc/ssh/sshd_config`.

2. Add the following line to the end of the file: `AuthenticationMethods publickey keyboard-interactive:pam`

3. Save and close the file.

4. Restart the SSH service: `sudo service ssh restart`.

In this article, we have explored how to use Bitwarden Authenticator Key to implement TOTP authentication on your Linux console, su, sudo, and SSH access. With Bitwarden Authenticator Key, you can add an extra layer of security to your account without having to worry about managing multiple passwords or codes. By following the steps outlined in this article, you can easily enable 2FA for your Linux console and keep your account secure from unauthorized access.
