Integrating GitHub with single sign-on (SSO) authentication

Integrating GitHub with single sign-on (SSO) authentication

To integrate GitHub with Single Sign-On (SSO) and various authentication methods, follow these steps:

1. SSO Integration with GitHub

Set up SSO in GitHub:

1. Navigate to GitHub Settings > Organization > SSO.

2. Choose a SAML SSO provider (e.g., Okta, Azure AD) and configure the necessary attributes and mappings.

3. Enable SSO and configure the necessary mappings for users and groups.

2. Two-Factor Authentication (2FA) with GitHub

Enable Two-Factor Authentication:

1. Go to GitHub Settings > Security > Two-Factor Authentication.

2. Set up 2FA using either a TOTP authenticator app or hardware security key.

3. SSH Keys Authentication

Add SSH Keys:

1. Navigate to GitHub Settings > SSH and GPG Keys.

2. Add your SSH public key to authenticate via SSH.

4. Personal Access Token (PAT) Authentication

Generate PAT:

1. Navigate to GitHub Settings > Developer Settings > Personal Access Tokens.

2. Generate a PAT with the required scopes for authentication.

5. GitHub Apps Authentication

Install GitHub App:

1. Navigate to GitHub Settings > Developer Settings > OAuth Apps.

2. Create and configure a GitHub App with required scopes and permissions.

6. GITHUB_TOKEN Authentication

Use GITHUB_TOKEN:

GITHUB_TOKEN is a special token provided for actions performed by GitHub Actions or CI/CD workflows, used automatically to authenticate with GitHub APIs.

Each method integrates securely into GitHub, ensuring smooth access and authentication across different workflows.
