Adds a generic OAuth2 authentication strategy to your user resource

Unlike OIDC, generic OAuth2 does not auto-discover provider endpoints. You can provide the URLs via CLI flags (set as literals in the DSL) or leave them to be configured via environment variables.

Example

mix ash_authentication.add_strategy oauth2 my_provider

Options

• --user, -u - The user resource. Defaults to YourApp.Accounts.User
• --accounts, -a - The accounts domain. Defaults to YourApp.Accounts
• --identity-field, -i - The field used to identify the user. Defaults to email
• --base-url - Base URL of the OAuth2 provider
• --authorize-url - Authorization endpoint URL (relative to base_url or absolute)
• --token-url - Token endpoint URL (relative to base_url or absolute)
• --user-url - User info endpoint URL (relative to base_url or absolute)
