Auth4App

Free authorization module via messengers for your SaaS

If your B2B product already has SMS authorization, please contact us. We will develop an integration module for free so that your customers can sign in via Telegram, WhatsApp, Viber and MAX.

Developing a module for your SaaS — gratis.

Do you already have an SMS in the admin panel?

A typical scenario: SaaS for business — a loyalty system, CRM or personal account — and SMS services are already connected to the integration panel so that connected business customers can log in using an SMS code.

Integration modules

Your product admin panel already has an integrations section — SMS, newsletters, payment systems.

Customer login via SMS

Business customers that have connected to your SaaS log in with an SMS code — a familiar but expensive and unstable channel.

There are not enough messengers nearby

Next to SMS, it is logical to offer sign-in via messengers — faster, cheaper and more convenient for end users.

Our offer
