Two-Factor Authentication (2FA) for Zoho


Zoho 2FA (Two-Factor Authentication) or Multi-Factor Authentication (MFA) is an additional layer of security in which a user or an organizational employee have to provide two factors to gain access to the Zoho account. With Zoho TFA being enabled, anyone trying to login to your Zoho account from an unrecognized computer/device must provide additional authorization. Authentication starts with a user submitting his traditional username and password. Once the user successfully gets authenticated with the 1st step verification, configured 2FA (OTP over SMS, Push Notifications, Yubikey, TOTP, Google Authenticator etc) method prompts for 2nd-step verification. After successfully authenticating with both of the steps a user is granted with the access to the Zoho account. This extra layer prevents the unauthorized person from accessing the resources even if cyber attackers get to know your credentials.

miniorange provides 15+ authentication methods and solutions for various use cases. It allows users and organizations to set up certain authentication and settings which includes password restrictions, restricting sign-in methods, as well as other security settings. miniorange also makes way for authentication apps that support Time-Based One-Time Password (TOTP) Google Authenticator, Microsoft Authenticator, Authy 2-Factor authentication app and our own miniorange Authenticator app.


Connect with External Source of Users


miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Shibboleth, Ping, Okta, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.
