Keeping your account and data secure

To protect your personal information, you should keep both your account on and any associated data secure.

About authentication to GitHub

You can securely access your account's resources by authenticating to GitHub, using different credentials depending on where you authenticate.

Creating a strong password

Secure your account on with a strong and unique password using a password manager.

Switching between accounts

You can stay signed in to multiple accounts and managed user accounts and quickly jump between sessions.

Updating your GitHub access credentials

GitHub credentials include not only your password, but also the access tokens, SSH keys, and application API tokens you use to communicate with GitHub. Should you have the need, you can reset all of these access credentials yourself.

Managing your personal access tokens

You can use a personal access token in place of a password when authenticating to GitHub in the command line or with the API.

Reviewing your SSH keys

To keep your credentials secure, you should regularly audit your SSH keys, deploy keys, and review authorized applications that access your account on

Reviewing your deploy keys

You should review deploy keys to ensure that there aren't any unauthorized (or possibly compromised) keys. You can also approve existing deploy keys that are valid.

Token expiration and revocation

Your tokens can expire and can also be revoked by you, applications you have authorized, and GitHub itself.

Reviewing your security log

You can review the security log for your personal account to better understand actions you've performed and actions others have performed that involve you.

Removing sensitive data from a repository

If you commit sensitive data, such as a password or SSH key into a Git repository, you can remove it from the history.

About anonymized URLs

If you upload an image or video to GitHub, the URL of the image or video will be modified so your information is not trackable.

About GitHub's IP addresses

GitHub serves applications from multiple IP address ranges, which are available using the API.

GitHub's SSH key fingerprints

Public key fingerprints can be used to validate a connection to a remote server.

Sudo mode

To confirm access to your account before you perform a potentially sensitive action, prompts for authentication.

Preventing unauthorized access

You may be alerted to a security incident in the media, such as the discovery of the Heartbleed bug, or your computer could be stolen while you're signed in to In such cases, changing your password prevents any unintended future access to your account and projects.

Viewing and managing your sessions

You can view and revoke your active sessions in your settings.
