class Otp(AbstractOtp):
    pass

Extend Admin

Create your custom admin using AbstractOtpAdmin:

from django_otp_keygen.admin import AbstractOtpAdmin


class OtpAdmin(AbstractOtpAdmin):
    """
    Admin interface for managing OTPs.
    Inherits from UserAdmin to provide a user-friendly interface.
    """

    pass

🔐 Usage: OTP Service

from django_otp_keygen.services import OtpService

otp_service = OtpService(user, "email")
otp_value = otp_service.generate_otp()

# To verify
is_valid = otp_service.verify_otp(input_otp)

✅ OTP Validation Logic

• Ensures OTP is not expired (expired_at)

• Prevents re-verification

• Automatically sets new expiration on generation

• OTP format is digit or alphanumeric based on settings

🧪 Model Properties

• otp_instance.is_expired

• otp_instance.is_verified

• otp_instance.is_pending

• otp_instance.is_active
