This error suggests incorrect credentials. Check username and password, or use a personal access token for authentication.

The 'invalid username or password' error usually indicates incorrect credentials during clone or pull requests. With GitHub phasing out password-based authentication, users are now required to use a personal access token (PAT) instead. To create one, go to Settings > Developer settings > Personal access tokens and generate a new token with the appropriate permissions for your repository. Use this token in place of a password when prompted. If you're using HTTPS URLs for cloning, replace the URL format to https://username:[email protected]/repo where token is your generated PAT. For SSH, ensure that your SSH keys are correctly added to your GitHub account in Settings > SSH and GPG keys. This method resolves authentication errors, allowing you to connect securely to GitHub.
