// Email OTP login policy, set by OTP_REQUIRED in config.php.

// Fails safe: the OTP step is off only when the constant is defined and is
// exactly the boolean false. A missing constant (any config.php written before
// this switch existed), 0, 'false' or a typo all keep it on.
// OFF BY DEFAULT: the OTP step runs only when the constant is defined and is
// exactly the boolean true. A missing constant (any config.php written before
// this switch existed), 1, 'true' or a typo all leave it off, so sign-in is
// password only and no SMTP is needed to log in.
//
// While it is off, every sign-in that skips the OTP because of it is logged as
// OTP_BYPASSED, and the login page and top bar both say so on screen — a
// weakened sign-in must never be invisible to whoever is using it.
// password-only sign-in must never be invisible to whoever is using it.
//
// Only the login OTP is affected. The staff/viewer and no-SMTP skips in
// login_otp.php still apply when it is on, and password-reset OTPs
// (PasswordResetManager) are a separate flow that stays on regardless.
