Introduction

As a developer in 2025, protecting your Heroku account from unauthorized access is a top priority to safeguard your applications and data. Heroku, a trusted platform for building and deploying apps, mandates multi-factor authentication (MFA) to keep your account secure. Among the available MFA options, the Heroku Authenticator App setup with Authenticator App ® 2FA stands out for its robust security features, including seamless iCloud sync and biometric authentication. This guide will walk you through the steps to set up Heroku with Authenticator App ® 2FA, helping you ensure your account remains protected with ease.

Ways to Authenticate with Heroku for Secure Access

Heroku enforces MFA to protect your account from unauthorized access, requiring a second factor of authentication beyond your username and password. Here are the authentication methods you can use with Heroku:

Authenticator App: Use a third-party app like Authenticator App ® 2FA to generate time-based one-time passwords (TOTP) locally on your device, offering strong protection against phishing attacks.
Security Key: Use a physical security key, such as a YubiKey, that supports WebAuthn or U2F standards for hardware-based authentication.
Built-In Authenticator: Leverage device-specific authenticators like Touch ID, Face ID, or Windows Hello, which use the FIDO2 WebAuthn standard for biometric verification.
Recovery Codes: Generate a set of one-time-use recovery codes as a backup method if your primary authentication method is unavailable.

For the best balance of security and convenience, we recommend using the Heroku Authenticator App setup with Authenticator App ® 2FA, which offers robust protection and seamless integration across devices.
