Accessing TOTP Secret from Microsoft Authenticator: A Step-by-Step Guide

Two-factor authentication (2FA) has become an essential security measure to protect our online accounts and sensitive information. One popular method of 2FA is Time-based One-Time Password (TOTP), which uses a secret key shared between the server and the user's device to generate a one-time password every 30 seconds. In this article, we will explore how to access your TOTP secret from Microsoft Authenticator.

Setting up TOTP in Home Assistant

To start, you need to set up TOTP in your Home Assistant configuration. Once enabled, you'll be prompted to enter the correct digits when logging in. Since Home Assistant knows the secret key, it can generate the correct number based on the shared secret.

Using Microsoft Authenticator with TOTP

Microsoft Authenticator is a popular app that supports two-step verification with 6-digit TOTP security. To use it with TOTP, simply click into the field and paste the generated code using Ctrl/Cmd + V. This will allow you to access your account securely.

Generating TOTP Code with Bitwarden

Another option for generating TOTP codes is Bitwarden, a password manager that supports MFA. Once set up, Bitwarden will generate a TOTP code for each site, allowing you to use one of the auto-fill options to fill in your username and password.

The Importance of Accurate Server Time

It's essential to note that TOTP authentication relies on both the server and authenticator device having an accurate time. If the server time is not synchronized with an NTP service, it may cause issues with MFA logins.

Choosing the Right MFA Module

Home Assistant offers several MFA modules, including Time-based One-Time Password (TOTP) MFA module. You can choose which MFA module to use when logging in, and turn MFA on or off in your user account profile page.

Extracting the Secret Key Step by Step

If you need to extract the secret key from Microsoft Authenticator, follow these steps:

Step 1: Find a QR Code

Find a QR code provided by the TOTP setup process. This will contain the secret key shared between the server and your device.

By following these steps, you can access your TOTP secret from Microsoft Authenticator and enjoy the added security of two-factor authentication. Remember to keep your secret key secure and never share it with anyone.

In conclusion, TOTP is a widely adopted method of 2FA that provides an additional layer of security for our online accounts. By using Microsoft Authenticator or Bitwarden to generate TOTP codes, you can ensure the security of your sensitive information. Always remember to keep your secret key secure and accurate server time to avoid any issues with MFA logins.
