Yes, it is possible to enable two-factor authentication (2FA) via any Authentication app that supports TOTP, e.g. Google Authenticator, Authy, etc.). Please note that two factor authentication is activated per account (user).
Two-factor authentication is account-based or study based. Some studies require two factor authentication from users. The procedure for your own account is always the same.
We offer the ability to enforce 2FA and/or 90-day password rotation on email domains associated with your institute. If you are interested - please submit a request here.
