I’ve been developing a Telegram bot that handles multiple user accounts and most of the core functionality is complete. However, I’m struggling to implement one specific feature that I think would be really valuable.
Basically, I want to create a system that can intercept one-time passwords when they come in. The goal is to protect users from scam bots that try to steal their verification codes. My plan is to have the bot automatically catch these codes and use them right away, which would make them worthless to any scammers.
The workflow I have in mind is:
Bot spots an incoming verification code
Automatically attempts authentication with that code
Code gets used up and becomes useless to potential attackers
I’m having trouble figuring out the technical details, especially how to handle the automatic login process without messing up the bot’s other functions.
I’m hoping someone here might have experience with similar projects or know of any open source examples I could learn from. Also open to working with others if anyone wants to help build this together.
Any suggestions or resources would be much appreciated!
This sounds sketchy as hell. You’re basically asking how to steal OTP codes - that’s textbook hacker behavior. Telegram will ban your bot instantly if you try this. Don’t “protect” users by doing shady stuff. Just teach them never to give codes to random bots.
What you’re describing sounds like malware, not security protection. You’re literally describing how scammers compromise accounts - automatically intercepting and using OTP codes. OTP codes exist for one reason: to verify the real account owner is doing something. When your bot grabs these codes automatically, you’re killing that security measure. Users might get locked out of their accounts or trigger security alerts. Want to actually help users fight scam bots? Build educational features instead. Have your bot watch for sketchy patterns and warn users about phishing attempts. Teach them how to spot fake vs real authentication requests. That’ll boost security without breaking existing systems.
I’ve worked on enterprise auth systems, and intercepting OTPs will land you in serious legal trouble - not just technical issues. You’re missing the point of how OTP security works. These codes verify user intent, not just who they are. Don’t try grabbing codes after delivery. Instead, stop the social engineering that tricks users into sharing them. I built something that watches conversation flows and catches when someone’s being walked through auth steps by a sketchy party. The real fix is behavioral analysis - track conversation patterns, response timing, and request sequences that scream social engineering. When you spot it, jump in with education prompts or verification challenges. Technically, you need permission-based monitoring where users explicitly opt into your protection service. Keeps you compliant while actually providing security value. Just make sure your session management doesn’t mess with legit authentication flows.
The other responses nailed the security concerns, but here’s a different take.
Don’t try intercepting OTPs directly - that creates more headaches than it’s worth. Build a smart monitoring system that protects users before problems hit.
I’ve automated similar security workflows. The trick is watching for patterns and responding intelligently without breaking existing security.
What actually works: Set up automated monitoring for message patterns, sender behaviors, and timing weirdness. When it spots suspicious activity, your system immediately alerts users and can temporarily lock down certain actions.
Automate responses like security warnings, logging suspicious attempts, or temporary account protections. The automation does the heavy lifting while users stay in control of their authentication.
Technically, you need a platform that handles multiple data sources, runs pattern recognition, and triggers different responses based on what it finds. Most coding solutions turn into a mess when you’re dealing with real-time monitoring and multiple trigger conditions.
Latenode makes this security automation straightforward. You can build workflows that monitor messages, analyze patterns, and respond automatically without touching the actual OTP codes. It handles the complex stuff while you focus on the security logic.
I’ve been building Telegram bots for years, and this idea won’t work. Beyond the security issues others mentioned, there are major technical problems. Your bot would need access to users’ private messages, which breaks Telegram’s TOS. Bots can’t read private messages unless users forward them manually, and auto-acting on OTP codes is a huge liability nightmare. Most users won’t grant the crazy permissions you’d need anyway. Don’t try intercepting codes. Build a verification system that spots suspicious auth requests instead. Create a database of scammer patterns and warn users when messages match those signatures. You’ll actually protect people without breaking their account security or platform rules.
