When a user enters their phone number, the plugin checks whether they already exist in the database. Then:

• New user — an OTP code is sent to their phone. After verification they are registered and logged in automatically.
• Existing user without password — OTP is sent again for verification.
• Existing user with password — they can login with their password, or request an OTP instead.
