I've tried to access data from WRDS through Google Colab by using wrds.Connection() function. But I got the OperationalError. I accessed data from WRDS through Google Colab many times before but this is the first time I face this problem. I changed password, computer, browser many times but it still didn't work.
Anyone please take a look and give me a comment so that I can get through this issue. Many thanks!
Enter your WRDS username [root]:.........
Enter your password:........
WRDS recommends setting up a .pgpass file.
You can find more info here:

There was an error with your password.
