The user enters their phone number on the login page and clicks the “continue” button.
After entering the phone number, the user receives a unique 6-digit code on the same login page and selects the messenger in which they are registered.
The user logs into the messenger and enters the received code. After entering the code, he can return to the site or application, where he will already be logged in.
Messenger messages are automatically sent in the language of the user's country. We support more than 50 languages — your service is ready to be launched anywhere in the world.
The language is automatically determined by phone number — the user receives clear instructions without additional settings on your part.
Authentication via messengers is more reliable than classic SMS-2FA, which minimizes the risk of hacking.
We offer a single rate all over the world, helping you save on SMS authorization costs.
Our solution is easier to integrate, so it reduces technical complexity and development costs.
Authentication via messengers is more convenient for users and reduces the risk of losing an audience.
Auth4App works wherever messengers are available, providing global reach.
Authentication via messengers works independently of mobile operators, reducing the risk of delivery problems.
At 10,000 logins per month, the difference is immediately noticeable: SMS costs increase per shipment, while Auth4App counts only successful authorizations.
Pay for every SMS sent, even if the code didn't arrive, was delayed, or the user requested it again.
If a customer doesn't sign in or doesn't receive a code, you don't pay for failed authorization.
Savings on the same amount
Even without repeated SMS requests, the cost of authorization via messengers is significantly lower in the first month of use.
Then instead of 10,000 SMS, you need to send 15,000 messages. The budget for SMS authorization increases to $560 - $1 100, and the cost through Auth4App remains tied only to the number of successful entries.
Make it easy for your users to sign in and start saving money with instant login via Telegram, WhatsApp, and Viber.
