Setup 2 Factor Authentication Github

[Jessia Adachi]

NoteStarting in March 2023 and through the end of 2023, GitHub will gradually begin to require all users who contribute code on GitHub.com to enable one or more forms of two-factor authentication (2FA). If you are in an eligible group, you will receive a notification email when that group is selected for enrollment, marking the beginning of a 45-day 2FA enrollment period, and you will see banners asking you to enroll in 2FA on GitHub.com. If you don't receive a notification, then you are not part of a group required to enable 2FA, though we strongly recommend it.

Two-factor authentication (2FA) is an extra layer of security used when logging into websites or apps. With 2FA, you have to log in with your username and password and provide another form of authentication that only you know or have access to.

You can configure two-factor authentication (2FA) using a TOTP app on mobile or desktop or via text message. After you have configured 2FA using a TOTP app or via text message, you can then also add security keys as alternate 2FA methods.

We strongly recommend using a time-based one-time password (TOTP) application to configure 2FA, and security keys as backup methods instead of SMS. TOTP applications are more reliable than SMS, especially for locations outside the United States. Many TOTP apps support the secure backup of your authentication codes in the cloud and can be restored if you lose access to your device.

After you configure 2FA, your account will enter a 28-day check up period. You can leave the check up period by successfully performing 2FA in those 28 days. Otherwise, you will be prompted to perform 2FA in an existing GitHub.com session on the 28th day. If you cannot perform 2FA to pass the checkup, you must use the provided shortcut to reconfigure your 2FA settings and retain access to GitHub.com.

If you're a member of an enterprise with managed users, you cannot configure 2FA for your managed user account account unless you're signed in as the setup user. For users other than the setup user, an administrator must configure 2FA on your identity provider (IdP).

A time-based one-time password (TOTP) application automatically generates an authentication code that changes after a certain period of time. These apps can be downloaded to your phone or desktop. We recommend using cloud-based TOTP apps. GitHub is app-agnostic when it comes to TOTP apps, so you have the freedom to choose any TOTP app you prefer. Just search for TOTP app in your browser to find various options. You can also refine your search by adding keywords like free or open source to match your preferences.

Tip: To configure authentication via TOTP on multiple devices, during setup, scan the QR code using each device at the same time or save the "setup key", which is the TOTP secret. If 2FA is already enabled and you want to add another device, you must re-configure your TOTP app from your security settings.

Under "Save your recovery codes", click Download to download your recovery codes to your device. Save them to a secure location because your recovery codes can help you get back into your account if you lose access.

Optionally, you can configure additional 2FA methods to reduce your risk of account lockout. For more details on how to configure each additional method, see "Configuring two-factor authentication using a security key" and "Configuring two-factor authentication using GitHub Mobile".

Warning: We strongly recommend using a TOTP application for two-factor authentication instead of SMS, and security keys as backup methods instead of SMS. GitHub doesn't support sending SMS messages to phones in every country. Before configuring authentication via text message, review the list of countries where GitHub supports authentication via SMS. For more information, see "Countries where SMS authentication is supported."

If you use two-factor authentication (2FA), passkeys satisfy both password and 2FA requirements, so you can complete your sign in with a single step. If you don't use 2FA, using a passkey will skip the requirement to verify a new device via email. You can also use passkeys for sudo mode and resetting your password.

Not all FIDO authenticators can be used as passkeys, but you can still register those authenticators as security keys. Security keys are also WebAuthn credentials, but unlike passkeys they don't require user validation. Since security keys only need to verify user presence, they only count as a second factor and must be used in conjunction with your password.

Registering a security key for your account is available after enabling 2FA with a TOTP application or a text message. If you lose your security key, you'll still be able to use your phone's code to sign in.

Confirm that you've downloaded and can access your recovery codes. If you haven't already, or if you'd like to generate another set of codes, download your codes and save them in a safe place. For more information, see "Configuring two-factor authentication recovery methods."

You can use GitHub Mobile for 2FA when signing into your GitHub account in a web browser. 2FA with GitHub Mobile does not rely on TOTP, and instead uses public-key cryptography to secure your account.

Once you have configured a TOTP application, or SMS, you can also use GitHub Mobile to authenticate. If, in the future, you no longer have access to GitHub Mobile, you will still be able to use security keys or TOTP applications to sign in.

With two-factor authentication (2FA) enabled, you'll need to use a second factor when accessing GitHub through your browser. When you first configure 2FA, your account will enter a check up period for 28 days to ensure your account's 2FA methods are setup correctly. You can exit the check up period by successfully performing 2FA within 28 days. If you don't authenticate within 28 days, you'll be asked to perform 2FA inside one of your existing GitHub.com sessions. If you cannot perform 2FA to pass the 28th day checkup, use the provided shortcut to reconfigure your 2FA settings and retain access to GitHub.com. For more information, see "Configuring two-factor authentication."

GitHub will only ask you to provide your 2FA authentication code again if you've logged out, are using a new device, are performing a sensitive action, or your session expires. For more information on 2FA for sensitive actions, see "Sudo mode."

If you chose to set up two-factor authentication using a TOTP application, you can generate an authentication code for GitHub at any time. In most cases, just launching the application will generate a new code. You should refer to your application's documentation for specific instructions.

If you delete your authenticator application after configuring two-factor authentication, you'll need to provide your recovery code to get access to your account. Many TOTP apps support the secure backup of your authentication codes in the cloud and can be restored if you lose access to your device. For more information, see "Recovering your account if you lose your 2FA credentials."

If you have enabled 2FA, and you have added a passkey to your account, you can use the passkey to sign in. Since passkeys satisfy both password and 2FA requirements, you can complete your sign in with a single step. For more information, see "About passkeys" and "Signing in with a passkey."

GitHub will send you a push notification to verify your sign in attempt. Opening the push notification or opening the GitHub Mobile app will display a prompt, asking you to approve or reject this sign in attempt.

When prompted for a username and password on the command line, use your GitHub username and personal access token. The command line prompt won't specify that you should enter your personal access token when it asks for your password.

If you lose access to your two-factor authentication credentials, you can use your recovery codes or another recovery method (if you've set one up) to regain access to your account. For more information, see "Recovering your account if you lose your 2FA credentials."

Note: If you cannot use any recovery methods, you have permanently lost access to your account. However, you can unlink an email address tied to the locked account. The unlinked email address can then be linked to a new or existing account. For more information, see "Unlinking your email address from a locked account."

If your authentication fails several times, you may wish to synchronize your phone's clock with your mobile provider. Often, this involves checking the "Set automatically" option on your phone's clock, rather than providing your own time zone.

I have to use the two factor authentication feature of github. That is fine. I am unable to comprehend how to use that with Eclipse. Whenever I commit my code or perform any activity, the only prompt I get from eclipse is to enter repository, userid and password.I have egit also installed but that does not help. Issue arrives in both Mac and Windows OSDoes anyone out there know how to do this?
