Cybercriminals steal login credentials through phishing emails and malware. Once they have your users' passwords, they have full access to their accounts. A second verification step stops them — even with a stolen password.
Criminals send fake emails that look legitimate, tricking users into entering their passwords on fraudulent sites. 2FA stops attackers even after credentials are stolen.
Malicious software can silently harvest every password saved in a browser. With 2FA active, stolen passwords alone are useless — the attacker also needs the one-time code.
After entering their password, the user receives a 6-digit code by email or SMS. Only someone who physically controls that inbox or phone can log in. Simple, effective, free.
Six simple steps that happen in seconds — invisible to the user, decisive for security.
Reduces account takeover risk by blocking attackers who have a stolen password but not the OTP code.
Helps meet GDPR, ISO 27001, and PCI-DSS security standards that require multi-factor authentication.
Users feel safer and more confident when they know an extra verification step protects their account.
Stops credential stuffing, brute-force and phishing attacks — even when passwords are already compromised.
Unlike TOTP authenticator apps, email/SMS OTP requires nothing extra from the user — just their phone or inbox.
Every OTP request and verification is logged. Detect suspicious patterns and failed attempts in real time.
Just two API calls: one to generate the OTP, one to verify it. Works with any language or framework.
Send OTP messages in the user's language. Template system supports unlimited locales.
Control expiry time, max attempts, message templates, delivery provider, and webhook notifications.
