Try Smart Sign-inWhy should you enable MFA for your Zoho accounts?
A single stolen password is enough to expose multiple employee accounts and company resources. Another step of verification is thus a necessity. Compromised passwords should not automatically mean account takeovers.
Do it with MFA — Protect your work accounts from credential-based attacks
Authenticator-based MFA utilizes time-based OTPs generated on an external device, which attackers don't control, reducing credential-based attacks by up to 99%.
