2FA brings an additional security layer to the authentication process, blocking attackers from taking control of meetings by guessing the password or using compromised credentials. Zoom offers a range of authentication methods such as SAML, OAuth, and/or password-based authentication, which can be individually enabled or disabled for an account. Users have the option to use authentication apps that support Time-Based One-Time Password (TOTP) protocol (such as Google Authenticator) or have Zoom send a code via SMS or phone call, as the second factor of the account authentication process.”]
