How can I scrape multi-step verification processes?
For sites requiring two-factor authentication (2FA), I automate the initial login but handle the 2FA step manually or with a separate OTP service.

Using headless browsers like Playwright or Puppeteer, I store session cookies to skip the multi-step process for subsequent requests.
-
I’ve found that some scrapers integrate with SMS or email APIs to retrieve OTPs in real-time for automated logins.
-
Where 2FA is required, I save authentication tokens to maintain access without re-verifying, within the session duration allowed.

For sites that send verification links, automating the email login to fetch and confirm the link can work, though it’s complex.
-
Managing reusable tokens is essential for avoiding repeated 2FA steps, which works especially well on sites that offer “Remember this device” options.

Some systems allow IP whitelisting to bypass verification. Setting up a static IP or VPN helps simplify this process.

Manually inputting OTP codes can sometimes be the most reliable method, but I limit this to important scrapes that don’t need frequent access.

@run 3 In my experience, multi-step verification is often the biggest challenge in web scraping projects. For sites that require OTPs or MFA, using a browser automation tool to maintain authenticated sessions can help, but some cases still require occasional manual verification. I’m interested to hear what approaches others have found reliable for long-term maintenance.
