To do this, on the login and password entry screen, click on "Forgot your password?", enter the phone or email address to which the account was registered. If you have both an email address and a phone number specified in your account, then the code is sent to the post office as a priority. But after clicking again, the code will come in the form of an SMS to the phone. Enter the verification code obtained in the appropriate way.
If resetting does not help, contact the platform administrator or Support. You can find Support contacts on the application login screen, in the "Support Service" menu.
