Yes, you may enable or disable two-factor authentication (sometimes called second-factor or 2FA) in Settings. We support time-based one-time passwords (TOTP) via your authenticator or password-management app of choice. We do not support SMS- or email-based 2FA, nor do we provide backup codes — if you lose access to your 2FA rolling codes, please reset your password using your email address in order to regain access to your account and reset your 2FA status, or contact support if you require assistance.
