credential error using imaplib with yahoo

Question

I have the code below that I'm running in a jupyter notebook. I'm trying to login to a yahoo email account and download all the emails from a folder. I'm getting the error below when I try to run the code. When I just go to yahoo.com and login with the same email address and password, it works fine. Does anyone see what the issue might be? (The email below is a fake example.)

The code comes from the github repo: https://gist.github.com/robulouski/7442321

code:

import imaplib, email, getpass
import sys
from email.utils import getaddresses


IMAP_SERVER = 'imap.mail.yahoo.com'
EMAIL_ACCOUNT = 'MadeUp@yahoo.com'
EMAIL_FOLDER = 'TheFolder'
OUTPUT_DIRECTORY = '/Users/name/Desktop/Stuff/NewFolder'


PASSWORD = getpass.getpass()


def process_mailbox(M):
    """
    Dump all emails in the folder to files in output directory.
    """

    rv, data = M.search(None, "ALL")
    if rv != 'OK':
        print("No messages found!")
        return

    for num in data[0].split():
        rv, data = M.fetch(num, '(RFC822)')
        if rv != 'OK':
            print("ERROR getting message", num)
            return
        print("Writing message ", num)
        f = open('%s/%s.eml' %(OUTPUT_DIRECTORY, num), 'wb')
        f.write(data[0][1])
        f.close()

def main():
    M = imaplib.IMAP4_SSL(IMAP_SERVER)
    M.login(EMAIL_ACCOUNT, PASSWORD)
    rv, data = M.select(EMAIL_FOLDER)
    if rv == 'OK':
        print("Processing mailbox: ", EMAIL_FOLDER)
        process_mailbox(M)
        M.close()
    else:
        print("ERROR: Unable to open mailbox ", rv)
    M.logout()


if __name__ == "__main__":
    main()

    594         self.state = 'AUTH'
    595         return typ, dat

Update:

I went in to my yahoo account security settings and updated "Allow apps that use less secure sign in" to allow. Now I'm getting the error message below when I run the code in jupyter notebook.
