Creating Your Own OTP Bot

[Cloned Boy]

Yes, I can guide you through creating your own OTP (One-Time Password) bot. Here's how you can build one:

Basic OTP Bot Components​

1. Backend Service (to generate and validate OTPs)
2. Delivery Mechanism (SMS, email, or app notification)
3. User Interface (web or mobile interface)

Simple Python Implementation (Backend)​

import random
import time
from datetime import datetime, timedelta

# Storage for OTPs (in production, use a database)
otp_storage = {}

def generate_otp(user_id, length=6, expiry_minutes=5):
"""Generate a numeric OTP and store it"""
otp = ''.join([str(random.randint(0, 9)) for _ in range(length)])
expiry = datetime.now() + timedelta(minutes=expiry_minutes)
    
otp_storage[user_id] = {
'otp': otp,
'expiry': expiry,
'verified': False
}
    
 return otp

def verify_otp(user_id, user_otp):
"""Verify if the provided OTP is correct"""
if user_id not in otp_storage:
return False
    
stored_data = otp_storage[user_id]
    
# Check if expired
if datetime.now() > stored_data['expiry']:
return False
    
# Check if OTP matches
if stored_data['otp'] == user_otp:
stored_data['verified'] = True
return True
    
return False

Delivery Options​

1. SMS (using Twilio or other SMS API):

from twilio.rest import Client

def send_otp_sms(phone_number, otp):
account_sid = 'YOUR_ACCOUNT_SID'
auth_token = 'YOUR_AUTH_TOKEN'
client = Client(account_sid, auth_token)

message = client.messages.create(
body=f'Your OTP is: {otp}',
from_='+1234567890',  # Your Twilio number
to=phone_number
)

1. Email (using SMTP):

import smtplib
from email.message import EmailMessage

def send_otp_email(email, otp):
msg = EmailMessage()
msg.set_content(f'Your OTP is: {otp}')
msg['Subject'] = 'Your One-Time Password'
msg['From'] = 'your_email@example.com'
msg['To'] = email

with smtplib.SMTP('smtp.example.com', 587) as server:
server.login('username', 'password')
server.send_message(msg)

Web Interface (Flask Example)​

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/request-otp', methods=['POST'])
def request_otp():
user_id = request.json.get('user_id')
if not user_id:
return jsonify({'error': 'User ID required'}), 400
    
otp = generate_otp(user_id)
# Here you would call send_otp_sms() or send_otp_email()
    
return jsonify({'status': 'OTP sent'})

@app.route('/verify-otp', methods=['POST'])
def verify_otp_route():
user_id = request.json.get('user_id')
user_otp = request.json.get('otp')
    
if not user_id or not user_otp:
return jsonify({'error': 'User ID and OTP required'}), 400
    
if verify_otp(user_id, user_otp):
return jsonify({'status': 'OTP verified'})
 else:
return jsonify({'error': 'Invalid OTP'}), 401

Security Considerations​

1. Always set a short expiration time (5-10 minutes)
2. Limit OTP attempts (3-5 tries before locking)
3. Use HTTPS for all communications
4. Don't return specific error messages (like "OTP expired" vs "invalid OTP")
5. Consider rate limiting to prevent abuse

Would you like me to elaborate on any specific part of this OTP bot implementation?
