Yes, you may enable/disable two-factor authentication (sometimes called second-factor or 2FA) in Settings. We support time-based one-time passwords (TOTP) via authenticator or password management apps. We do not support SMS- or email-based 2FA at this time, 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, or contact support if you require assistance.
