Problem Description

Issue

Every time I try to log in to Steam using the Steam Guard mobile app (AMP), the system rejects my access and asks me to reauthorize the login repeatedly. Despite:

Correctly entering my email and password.

Providing the two-factor authentication (2FA) code generated by the app.

Verifying that the mobile device’s time is synchronized.

The process never completes, displaying a message like: “We need to verify you again” or “Please authorize from the Steam app,” creating an infinite loop.

Reproduction Steps

  • Login fail
  • Steam Guard
  • Please authorize from the Steam app
