Requirements: CoreSSH Server, Microsoft Authenticator

Introduction

This guide walks through configuring Microsoft Authenticator as the 2FA app for a CoreSSH Server user account. Before starting, make sure 2FA is enabled for the user. See Getting Started with 2FA for instructions.

Add the account in Microsoft Authenticator

Open Microsoft Authenticator on your mobile device and tap the + button in the top right corner. Select Other (Google, Facebook, etc.) as the account type.

Scan the QR Code

Point your device's camera at the QR Code displayed in the CoreSSH Server admin console. Microsoft Authenticator will automatically detect the code and add the account.

If you cannot scan the QR Code, tap Or enter code manually instead. Enter the account name and the secret key shown in CoreSSH Server, then tap Finish.

Verify the setup

Open Microsoft Authenticator and locate the CoreSSH Server entry. A six-digit code will be displayed and refreshes every 30 seconds. Use this code when prompted during SFTP login.

To confirm the setup is working, connect to CoreSSH Server using an SFTP client. After entering your password, CoreSSH Server will prompt for a one-time passcode. Enter the code shown in Microsoft Authenticator.
