Why RainbowSecure is the Pioneer in Visual MFA

While others rely on outdated push notifications, basic OTPs, or biometric shortcuts,

RainbowSecure introduced the world’s first interactive, color-and-style based MFA — a visual authentication experience that makes phishing nearly impossible.

RainbowSecure changes everything by transforming how users interact with login security — making it visual, intuitive, and unbreakable.

First-of-its-Kind: Style + Color + Position = Secure Login

RainbowSecure is the only MFA plugin that lets users personalize login with:

  • 17 million colors as font color
  • 100+ font styles — including font name, size, bold, italic, underline
  • Position-based login elements — a world-first in MFA, where text placement becomes part of the authentication
  • 17 million color as background color
  • Need to choose 1 or 2 style elements

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.

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.
