    # Redirect to home after login.
    # login_redirect "/"

    # Redirect to home page after logout.

    # Redirect to wherever login redirects to after account verification.
    # verify_account_redirect { login_redirect }

    # Redirect to login page after password reset.

    # Ensure requiring login follows login route changes.
    # require_login_redirect { login_path }

    # ==> Deadlines
    # Change default deadlines for some actions.
    # verify_account_grace_period 3.days.to_i
    # reset_password_deadline_interval Hash[hours: 6]
