What is Multi-Factor Authentication (MFA)?

Rainbow Secure’s MFA adds powerful layers of security beyond passwords — your digital guardian online.
Think of it like needing multiple keys to open a treasure chest: even if one is stolen, your account stays protected. MFA works by combining two or more verification factors — like formatted passwords, one-time codes, or smart login behavior.
Rainbow Secure gives you flexible options: visual (color + style) passwords, OTPs via SMS or email, and QR codes — all designed to stop phishing, credential theft, and unauthorized access.

Rainbow Secure MFA Protects With

Traditional MFA — especially SMS-based OTPs — can still be phished or intercepted. Rainbow Secure defends against these advanced attacks with visual complexity and behavior-aware layers that bots and fake login pages can’t replicate.

With Rainbow Secure, you get:

Knowledge-Based Factors

What you know — passwords enhanced with color, font, & style

Possession-Based Factors

What you have — OTPs via SMS, email, or Rainbow secure app

Contextual/Adaptive Factors

What you do or where you are — device, location, and login behavior

How Does Multi-Factor Authentication (MFA) work?

When a user attempts to access a resource, they are presented with multiple authentication factors along with a traditional username and password. If the user’s login credentials and second or more authentication methods pass successfully, they are granted access to the resource.

Rainbow Secure MFA system generate a unique one-time passcode (OTP) and formatting challenge for each login attempt that is delivered to your registered smartphone, secondary email or private mobile app. User must provide correct passcode and fulfill the challenge. Additionally user’s location, device and request context parameters are considered for approving the access request.

Why Is Multi-Factor Authentication (MFA) Important?

Phishing-Resistant

Stops attacks with visual login elements bots and fake sites can’t replicate

Adaptive Security

Adjusts based on device, time, location, and login behavior

Smart Interaction/ Inbuilt Captcha

Visual and interactive authentication designed for humans, not just compliance

Dark Web Protection

Prevents use of leaked or stolen credentials

Color + Style Login

Unique user-selected formats prevent credential replay and reuse

Flexible MFA Flows

Use password-first, OTP-first, or go passwordless

Audit-Ready

Built-in logging and reporting for SOC 2, HIPAA, GDPR, and more

AI-Based Monitoring

With Morden tech, detects suspicious login patterns and triggers real-time risk response

TESTIMONIALS

What Client’s Say About Us

RainbowSecure has made my life easier. It's unbelievably convenient. Now all of my work is centralized. Earlier, I was using GoDaddy's email and security services. I had to manage over 10+ application accounts with different usernames and passwords. It was frustrating, but RainbowSecure is a game-changer. Now, I use their email and security services. I use one username and password to log in with Microsoft 365, Google Suite, Shopify, GoDaddy accounts, and more. I must say, their security is the best.

Benefits of Multi-Factor Authentication (MFA)

Enhanced security

Multi-factor authentication (MFA) adds an extra layer of security, reducing the chances of an attacker gaining access to the system.

Increased productivity and flexibility

Employees may securely access business apps and resources from practically any device and location, without jeopardising the company's network.

Fraud Prevention

Multi-Factor Authentication (MFA) adds an additional degree of protection by ensuring that everyone is who they say they are, preventing unwanted access.

Improved user trust

When employing Multi Factor Authentication (MFA), users may secure the protection of their personal information without exerting additional effort.

Reduced management cost

You'll observe less suspicious behaviour on client accounts if you use Multi-Factor Authentication (MFA), and you'll spend less money on security management as a result.

Adaptability for different use cases

Additional security is required when processing high-value transactions or accessing sensitive information from unknown networks and devices, such as geolocation, IP address, and time since the last login.

Frequently Asked Questions

  • 2FA or MFA?

    MFA and 2FA are technology names for methods used to secure software accounts and are often used interchangeably. 2FA means two factors to secure account while MFA means two or more factors. 

  • Can I use MFA for Office 365?

    Yes with RainbowSecure you can easily integrate MFA authentication for Office 365 and other business apps using MFA options of OTP, QR code, location, date time, authenticator app and more at competitive pricing. Office 365 by default uses Azure AD but is not suitable for all users. We can help you overcome it with stronger security and better user experience using interactive color and style options.

  • What is MFA in Cloud?

    With the rapid growth in Cloud MFA has become necessary. As companies move their systems to the cloud they can’t rely on a single form of security. Additional MFA security needs to be ensured. MFA will ensure that users are who they say they are by asking to provide, work on additional authentication factors/steps that are more difficult for hackers to imitate, and make account takeover attacks like brute force and phishing attacks impossible and irrelevant.

     

  • Why using colors and styles make login secure

    Now you have something you know and something you do making the login very strong and secure. Colors and styles make passwords and OTP tokens multi-layered. Colors and styles give extra attributes to every character making the available combinations exponentially larger. In fact, now every character has 36 quadrillion combinations making the resulting hash very very huge. Also, now that login is interactive, it breaks the attack automation using stolen and compromised passwords and tokens.
