OTP Token SMS or email: principle in 30 seconds
.

A single-use code, generated for a specific action and valid for a few moments. It completes the password for a strong authentication and becomes a natural part of your users' daily lives.
Two standards are common:
Standard H (counter)
Standard T (time, 30-60 s).

For developers

  • Standards RFC 4226 & RFC 6238

How the single-use code creates a secure path from dispatch to confirmation

For each critical action, a temporary code is generated by SMS or email, conveyed through the most suitable channel, at high deliverability then checked before expiry.

Immediate gains with email or SMS security (2FA)

Reduce fraud with single-use passwords, codes that expire quickly, a limited number of attempts and automatic blocking in the event of repeated errors. At the same time, preserve conversion with well-managed code forwarding, simple switching between SMS and email, clear messages and rapid response. On the compliance side, your data is hosted in France (OVHcloud), processed according to RGPD, with audit logs and minimal retention.

2FA

From dispatch to validation :

For each sensitive action, your application requires a single-use code. Efidem generates it, sends it via the most appropriate channel, then checks the entry before it expires. Attempts are limited, and each step is tracked for auditing purposes.
