Stacks supports a number of authentication methods including Single Sign on Services using OpenID Connect, ILS Integrations and an internal authentication method.
ILS authentication methods enable 'My Account' user features including standard authentication, hold requests, viewing items, fees and fines, renewing items and more depending on what services may be offered through the Integrated Library Service's API.
Important! Third-party authentication is not supported during the initial implementation phase of Stacks, these will be configured after you have successfully launched your site, and may require an additional professional services fee to setup.
