Sigra.Plug.RequireMFA (Sigra v0.2.2)

Copy Markdown View Source

MFA session gate plug.

Checks the session type from conn.private[:sigra_session]. If the session type is :mfa_pending, redirects to the MFA challenge page and halts. Standard and remember_me sessions pass through.

This plug must come AFTER Sigra.Plug.RequireAuthenticated in the pipeline. The ordering is: FetchSession -> RequireAuthenticated -> RequireMFA.

Options

  • :mfa_path - Path to the MFA challenge page. Default: "/users/mfa".
  • :logout_path - Path to the logout endpoint. Default: "/users/log_out".

Example

plug Sigra.Plug.RequireMFA, mfa_path: "/users/mfa"
