How to Enable Two-Factor Authentication on Your GitHub Account
In an era where digital security is more important than ever, protecting your online accounts with only a username and password is no longer sufficient. This is especially true for development platforms like GitHub, where your code, collaborations and project history reside. Enabling two-factor authentication (2FA) on your GitHub account adds a second layer of protection, making it far harder for malicious actors to gain unauthorized access — even if they have your password.
This article walks you through why 2FA matters on GitHub, what methods are available, how to enable and configure it step-by-step, and best practices to ensure you stay locked in (and locked down) safely.
Why Enable 2FA on GitHub?
GitHub hosts an enormous number of open-source and private repositories, many of which form the backbone of the software systems we all rely on. A compromised GitHub account can lead to leaked code, unauthorized commits, malicious changes, data exposure, or disruption of dependency chains. GitHub itself has noted that one factor (just a password) is inadequate protection.

In fact, as of March 2023, GitHub began requiring users who contribute code on GitHub.com to enable at least one form of 2FA.
By enabling 2FA, you significantly reduce the risk that someone can hijack your account—even if they somehow discover your password or exploit another vulnerability. It also protects your professional identity, your projects and your team’s trust in you.
What Methods Does GitHub Support?
GitHub offers several 2FA methods. Each has pros and cons—choosing the right one (or combination) will strengthen your account.
Here are the main options:
TOTP (Time-based One-Time Password) authenticator apps — These generate changing codes (typically every 30 seconds) using an app like Google Authenticator, Authy, Microsoft Authenticator, etc.
SMS / text message codes — GitHub supports receiving a code via SMS as second factor, although this method is considered less secure (vulnerable to interception) and is not available in all countries.

Security keys / hardware keys (WebAuthn, FIDO2, U2F) — These are physical devices (e.g., YubiKey) that you insert or tap during login. They are among the most secure forms of 2FA.

GitHub Mobile push authentication — GitHub’s mobile app can act as a second factor (push notification) once you have an existing 2FA method configured.

Passkeys — A newer method where your device stores a credential using public-key cryptography, satisfying both password + 2FA requirement (on supported platforms).
GitHub Docs
GitHub strongly recommends using a TOTP app and/or security keys rather than relying solely on SMS
