Custom login portal for multiple sites - PHP header issues

I’m trying to build a personal login gateway for various websites like Gmail and Facebook. The idea is to use one master login, then pick which site to access without entering separate credentials. My approach was to use cURL in PHP to send POST requests with headers and data mimicking a regular login. But it’s not working for any site I’ve tried.

Here’s what I’m wondering:

  1. Has anyone successfully done something similar?
  2. Could the issue be related to IP address differences between my PHP server and browser?
  3. Is it possible that the cookies sent via cURL are time-sensitive?

I initially thought it was straightforward, but now I’m stumped. Any insights on why this method isn’t working or alternative approaches would be really helpful. I’m new to working with login systems, so I might be missing something obvious.

hey alexlee, that sounds like a tricky project. i’ve messed around with similar stuff before. the main issue is prob that sites have security measures to prevent exactly what ur trying to do. they use things like ip checks, browser fingerprinting, and CAPTCHAs to block automated logins. might wanna look into oauth instead for a safer approach. good luck!

I’ve encountered similar challenges when working on automation projects. The primary obstacle you’re facing is likely the sophisticated anti-bot measures implemented by major websites. These systems are designed to detect and block automated login attempts, even those with good intentions.

Instead of trying to mimic browser behavior, which is increasingly difficult, I’d suggest exploring official APIs provided by these platforms. Many offer OAuth or similar authentication methods that allow secure, authorized access to user data. This approach is not only more reliable but also aligns with best practices and terms of service.

If you’re set on your current approach, you might need to delve into more advanced techniques like browser automation with tools such as Selenium. However, be aware that this may still violate terms of service for many sites.

I’ve dabbled in similar projects, and let me tell you, it’s a real minefield. The big sites you’re targeting have insanely sophisticated security measures in place. They’re not just looking at IP addresses and cookies - they’re checking browser fingerprints, analyzing user behavior patterns, and employing all sorts of tricks to spot automated logins.

From my experience, even if you manage to get past the initial login, maintaining a session is another beast entirely. These sites often use dynamic tokens and frequent re-authentication checks that are incredibly hard to replicate with cURL.

If you’re dead set on this path, you might want to look into headless browsers like Puppeteer. They can mimic real browser behavior more closely. But honestly, I’d strongly advise against this approach. It’s a constant cat-and-mouse game, and you’re likely to get blocked or even face legal issues.

Have you considered building a password manager instead? It’s a similar concept but much more above-board and actually useful for daily life. Just a thought from someone who’s been down this road before.
