Users forget them, reuse them, and often fall for phishing—leading to constant login issues and security gaps.
People are tired of juggling apps, codes, and pop-ups. Rainbow Secure’s passwordless OTP keeps login simple and fast, without sacrificing security.
AI, bots, and even emerging quantum tools make password guessing and credential attacks faster and easier than ever.
Every OTP includes simple color and style instructions. Users follow them easily, but bots, phishers, and automated scripts can’t copy the pattern — making logins far safer.
Instead of sending the whole code to one place, Rainbow Secure splits it across two channels. Even if one channel is compromised, attackers can’t use it.
Rainbow Secure monitors every login in real time, stopping bots, brute-force attempts, credential stuffing, and phishing.
No passwords to remember, reset, or manage. Users get a smooth login experience — and businesses eliminate the biggest source of attacks: password reuse.
Users receive a one-time code via email, SMS, or both.
Each OTP message includes color and style instructions that guide users to apply a simple visual formatting step—adding an extra verification layer that bots, phishers, and automated scripts cannot mimic.
Eliminates password resets, lockouts, and password-based phishing attacks.
Rainbow Secure divides the OTP into two parts and sends them across email + SMS, making interception nearly impossible.
Websites, SaaS apps, WordPress, custom apps, and enterprise IAM workflows.
Codes expire quickly, are tied to device/session, and cannot be reused.
