I’ve been developing a multi-account management system for Telegram and I’m trying to figure out how to add a security feature that automatically invalidates verification codes.
Basically what I want to do is create protection against scam bots that trick users into sharing their authentication codes. My thought is to automatically consume these codes right when they come in so they can’t be misused later.
The workflow I have in mind:
- Monitor for incoming verification messages
- Extract the code and use it immediately for authentication
- This makes the code expired so scammers can’t abuse it
I’m running into issues with the technical implementation though. Not sure how to handle the automatic login process without messing up my existing bot functionality.
What I’m hoping to find:
- Some guidance on the best approach for coding this
- Maybe an existing project or code samples I could learn from
- Possibly other developers interested in working together on this
Anyone dealt with similar anti-phishing features before or know of resources that might help?
I’ve worked with Telegram’s API on this - you’re basically building a race condition system to beat scammers to the code. The main challenge is handling session states without breaking your bot. Run the OTP monitoring in a separate thread or process. Use different session files for each function. The hardest part? Figuring out which messages actually have verification codes vs regular messages with numbers. You’ll need solid regex patterns, maybe some ML to catch format variations. What worked for me: create a temp client session just for auth attempts, then destroy it right after. Keeps your main bot session clean. Set up timeouts too - if the code isn’t used within 30-60 seconds, assume it’s legit and consume it. Definitely add proper logging for debugging. Things will go wrong.
this sounds tricky, but interesting! if ur using python, check out the telethon library - it’s good for session management. just be careful with auto-consuming codes, could lock u out. maybe add a delay or ask for confirmation before invalidating?
I built something like this last year and hit a bunch of issues you’ll want to know about. Telegram’s rate limiting is brutal when you’re doing frequent login attempts, especially across multiple accounts. You need solid session handling or you’ll trigger their anti-spam systems. Technically, MTProto beats the high-level libraries - gives you way more control. Focus on intercepting auth.signIn calls and getting the timing right for code consumption. Store your session states properly and handle connection drops. One gotcha: some verification codes have built-in delays before they work, so trying to use them immediately fails. Also set up a whitelist for trusted contacts so you don’t block legit code sharing. It’s worth the hassle though - I saw 80% fewer successful phishing attempts during testing.
