About personal access tokens
Personal access tokens are an alternative to using passwords for authentication to GitHub when using the GitHub API or the command line.
Personal access tokens are intended to access GitHub resources on behalf of yourself. To access resources on behalf of an organization, or for long-lived integrations, you should use a GitHub App. For more information, see "About creating GitHub Apps."
Types of personal access tokens
GitHub currently supports two types of personal access tokens: fine-grained personal access tokens and personal access tokens (classic). GitHub recommends that you use fine-grained personal access tokens instead of personal access tokens (classic) whenever possible.
Organization owners can set a policy to restrict the access of personal access tokens (classic) to their organization. For more information, see "Establecimiento de una directiva de token de acceso personal en la organización."
Fine-grained personal access tokens
Fine-grained personal access tokens have several security advantages over personal access tokens (classic):
- Each token can only access resources owned by a single user or organization.
- Each token can only access specific repositories.
- Each token is granted specific permissions, which offer more control than the scopes granted to personal access tokens (classic).
- Each token must have an expiration date.
- Organization owners can require approval for any fine-grained personal access tokens that can access resources in the organization.
Personal access tokens (classic)
Los Personal access tokens (classic) son menos seguros. Sin embargo, algunas características solo funcionarán con personal access tokens (classic):
- Solo los personal access tokens (classic) tienen acceso de escritura para los repositorios públicos que no son propiedad tuya o de una organización de la que no eres miembro.
- Los colaboradores externos solo pueden usar personal access tokens (classic) para acceder a los repositorios de la organización en los que son colaboradores.
- Algunas operaciones de API REST no están disponibles para fine-grained personal access tokens. Para una lista de las operaciones de API REST que se admiten para un fine-grained personal access token, consulta "Puntos de conexión disponibles para tokens de acceso personal específicos".
If you choose to use a personal access token (classic), keep in mind that it will grant access to all repositories within the organizations that you have access to, as well as all personal repositories in your personal account.
Como precaución de seguridad, GitHub quita automáticamente el personal access token que no se ha usado durante un año. Para proporcionar más seguridad, te recomendamos que agregues una expiración a tu personal access token.
Keeping your personal access tokens secure
Personal access tokens are like passwords, and they share the same inherent security risks. Before creating a new personal access token, consider if there is a more secure method of authentication available to you:
- To access GitHub from the command line, you can use GitHub CLI or Git Credential Manager instead of creating a personal access token.
- When using a personal access token in a GitHub Actions workflow, consider whether you can use the built-in
GITHUB_TOKEN
instead. For more information, see "Autenticación automática de tokens."
If these options are not possible, and you must create a personal access token, consider using another service such as the 1Password CLI to store your token securely, or 1Password's GitHub shell plugin to securely authenticate to GitHub CLI.
When using a personal access token in a script, you can store your token as a secret and run your script through GitHub Actions. For more information, see "Secretos cifrados." You can also store your token as a Codespaces secret and run your script in Codespaces. For more information, see "Administrar secretos cifrados para tus codespaces."
For more information about best practices, see "Keeping your API credentials secure."
Creating a fine-grained personal access token

-
Verify your email address, if it hasn't been verified yet.
-
En la esquina superior derecha de cualquier página, haga clic en la foto del perfil y, luego, en Settings (Configuración).
-
En la barra lateral izquierda, haz clic en Configuración del desarrollador.
-
In the left sidebar, under Personal access tokens, click Fine-grained tokens.
-
Click Generate new token.
-
Under Token name, enter a name for the token.
-
Under Expiration, select an expiration for the token.
-
Optionally, under Description, add a note to describe the purpose of the token.
-
Under Resource owner, select a resource owner. The token will only be able to access resources owned by the selected resource owner. Organizations that you are a member of will not appear unless the organization opted in to fine-grained personal access tokens. For more information, see "Establecimiento de una directiva de token de acceso personal en la organización."
-
Optionally, if the resource owner is an organization that requires approval for fine-grained personal access tokens, below the resource owner, in the box, enter a justification for the request.
-
Under Repository access, select which repositories you want the token to access. You should choose the minimal repository access that meets your needs. Tokens always include read-only access to all public repositories on GitHub.
-
If you selected Only select repositories in the previous step, under the Selected repositories dropdown, select the repositories that you want the token to access.
-
Under Permissions, select which permissions to grant the token. Depending on which resource owner and which repository access you specified, there are repository, organization, and account permissions. You should choose the minimal permissions necessary for your needs. For more information about what permissions are required for each REST API operation, see "Permisos necesarios para los tokens de acceso personal específicos."
-
Click Generate token.
If you selected an organization as the resource owner and the organization requires approval for fine-grained personal access tokens, then your token will be marked as pending
until it is reviewed by an organization administrator. Your token will only be able to read public resources until it is approved. If you are an owner of the organization, your request is automatically approved. For more information, see "Revisión y revocación de tokens de acceso personal en la organización".
Creating a personal access token (classic)
Note: Organization owners can restrict the access of personal access token (classic) to their organization. If you try to use a personal access token (classic) to access resources in an organization that has disabled personal access token (classic) access, your request will fail with a 403 response. Instead, you must use a GitHub App, OAuth App, or fine-grained personal access token.
Note: Your personal access token (classic) can access every repository that you can access. GitHub recommends that you use fine-grained personal access tokens instead, which you can restrict to specific repositories. Fine-grained personal access tokens also enable you to specify fine-grained permissions instead of broad scopes.

To use your token to access resources owned by an organization that uses SAML single sign-on, authorize the token. For more information, see "Autorizar un token de acceso personal para usar con un inicio de sesión único de SAML" in the GitHub Enterprise Cloud documentation.

Using a personal access token on the command line
Once you have a personal access token, you can enter it instead of your password when performing Git operations over HTTPS.
For example, to clone a repository on the command line you would enter the following git clone
command. You would then be prompted to enter your username and password. When prompted for your password, enter your personal access token instead of a password.
$ git clone https://github.com/USERNAME/REPO.git
Username: YOUR_USERNAME
Password: YOUR_PERSONAL_ACCESS_TOKEN
Personal access tokens can only be used for HTTPS Git operations. If your repository uses an SSH remote URL, you will need to switch the remote from SSH to HTTPS.
If you are not prompted for your username and password, your credentials may be cached on your computer. You can update your credentials in the Keychain to replace your old password with the token.
Instead of manually entering your personal access token for every HTTPS Git operation, you can cache your personal access token with a Git client. Git will temporarily store your credentials in memory until an expiry interval has passed. You can also store the token in a plain text file that Git can read before every request. For more information, see "Almacenar tus credenciales de GitHub en el caché dentro de Git."
