For TOptions changes, the default OptionsMonitor implementation of IOptionsMonitor has an overload that accepts one or more IOptionsChangeTokenSource instances.IChangeToken tokens can be added to cache entries to trigger cache evictions on change.For monitoring changes to files, IFileProvider's Watch method creates an IChangeToken for the specified files or folder to watch.Example uses of change tokens in ASP.NET CoreĬhange tokens are used in prominent areas of ASP.NET Core to monitor for changes to objects: Calling Dispose stops the token from listening for further changes and releases the token's resources. The ChangeToken.OnChange(Func, Action, TState) overload takes an additional TState parameter that's passed into the token consumer Action. Action is called when the token changes.The ChangeToken.OnChange(Func, Action) method registers an Action to call whenever the token changes: The NuGet package is implicitly provided to the ASP.NET Core apps. ChangeToken classĬhangeToken is a static class used to propagate notifications that a change has occurred. HasChanged must be set before the callback is invoked. The IChangeToken interface includes the RegisterChangeCallback(Action, Object) method, which registers a callback that's invoked when the token has changed. HasChanged receives a value that indicates if a change has occurred.It's also possible for a token to never be cancelled if no changes occur or the underlying change listener is disposed or disabled. If ActiveChangedCallbacks is set to false, a callback is never called, and the app must poll HasChanged for changes. ActiveChangeCallbacks indicate if the token proactively raises callbacks.IChangeToken propagates notifications that a change has occurred.

You can also store the token in a plain text file that Git can read before every request. Git will temporarily store your credentials in memory until an expiry interval has passed. Instead of manually entering your PAT for every HTTPS Git operation, you can cache your PAT with a Git client.

You can update your credentials in the Keychain to replace your old password with the token. If you are not prompted for your username and password, your credentials may be cached on your computer. If your repository uses an SSH remote URL, you will need to switch the remote from SSH to HTTPS. Personal access tokens can only be used for HTTPS Git operations. Once you have a token, you can enter it instead of your password when performing Git operations over HTTPS.įor example, on the command line you would enter the following: $ git clone username/ repo.git
For more information, see " Authorizing a personal access token for use with SAML single sign-on" in the GitHub Enterprise Cloud documentation. To use your token to authenticate to an organization that uses SAML single sign-on, authorize the token. When working with the API, use tokens as environment variables instead of hardcoding them into your programs.
Warning: Treat your tokens like passwords and keep them secret. To use your token to access repositories from the command line, select repo. Select the scopes, or permissions, you'd like to grant this token. To give your token an expiration, select the Expiration drop-down menu, then click a default or use the calendar picker. In the left sidebar, click Personal access tokens. In the left sidebar, click Developer settings.
In the upper-right corner of any page, click your profile photo, then click Settings. Verify your email address, if it hasn't been verified yet. For more information, see " Available scopes". To provide additional security, we highly recommend adding an expiration to your personal access tokens.Ī token with no assigned scopes can only access public information. For more information, see " About authentication with SAML single sign-on" and " Authorizing a personal access token for use with SAML single sign-on" in the GitHub Enterprise Cloud documentation.Īs a security precaution, GitHub automatically removes personal access tokens that haven't been used in a year. If you want to use a PAT to access resources owned by an organization that uses SAML SSO, you must authorize the PAT. Personal access tokens (PATs) are an alternative to using passwords for authentication to GitHub when using the GitHub API or the command line. For more information about authenticating with GitHub CLI, see gh auth login. Note: If you use GitHub CLI to authenticate to GitHub on the command line, you can skip generating a personal access token and authenticate via the web browser instead.
