"User is not logged in" Error When Using Research Class for Yahoo Premium Access #320
Description
Describe the bug
Authentication using the Research class in yahooquery[premium] is no longer working for me. Attempts to retrieve data now return 'User is not logged in', even though this was working as recently as last month.
To Reproduce
from yahooquery import Research
r = Research(username='enter_username', password='enter_password')
from yahooquery import Ticker
t = Ticker("AAPL", session=r.session, crumb=r.crumb)
tags = ['OperatingCashFlow', 'CapitalExpenditure', 'FreeCashFlow']
data = t.p_get_financial_data(tags, trailing=False)
print(data)
Expected behavior
Previously, the Research object successfully authenticated using my Yahoo Finance Premium credentials and allowed access to premium data via p_get_financial_data().
Environment:
I have an active Yahoo Finance Premium subscription
App password (not regular password) is being used
selenium is installed and configured
Package installed with: pip install yahooquery[premium]
This setup has worked consistently for the past year
Additional context
Authentication errors began occurring in early May 2025. I haven’t changed my environment or credentials. I suspect there may have been a change on Yahoo’s end that affects login or session handling.
Would appreciate guidance on whether a change in the login flow is now required, or if there's a known workaround.
