Log in failed even with correct user name and password

[jack-chen1688]

I met this strange issue. schwab-api's example in README.md worked for me multiple times and then suddenly failed. I didn't change user name and password at all. I then change api = Schwab() to api = Schwab(headless=False) to debug this issue and noticed the following. This is very strange. I used the same user name and password can log into the website using firefox browser without problem. Tried multipole times and it just wont' let me log in with playwright's firefox browser. Could this caused by browser cache of playwright?
