How does this work?

01

Entering a phone number for authorization

The user enters their phone number on the login page and clicks the “continue” button.

02

Getting a code and choosing a messenger

After entering the phone number, the user receives a unique 6-digit code on the same login page and selects the messenger in which he is registered.

03

Entering a verification code

The user logs in to 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.
