[SOLVED] AUTHENTICATIONFAILED - LOGIN Invalid credentials

AUTHENTICATIONFAILED - LOGIN Invalid credentials

I´m trying to connect my python-scrip with Thunderbird. Thunderbird uses my yahoo-mail.

With following code I should be able to connect to Thunderbird:

M = imaplib.IMAP4_SSL(config.server)
M.login(config.user, config.passwd)
M.select("inbox")

but I have the following issue:

Loaded classifier and label encoder with tag 'productive'
Traceback (most recent call last):
File "main.py", line 51, in <module>
M.login(config.user, config.passwd)
File 
"C:\AppData\Local\Continuum\ anaconda3\envs\nn_dev\lib\imaplib.py", line 
593, in login
raise self.error(dat[-1])
imaplib.error: b'[AUTHENTICATIONFAILED] LOGIN Invalid credentials'

How can I solve this problem?

Solution

If you can connect to Yahoo with Thunderbird, you should be able to connect directly to Yahoo with Python: just use the same login data you used in Thunderbird.

Otherwise, maybe there is some type of block on the Yahoo side (for example, if you activated two-step authentication)
