I am trying to connect my gmail to python, but show me this error:

I already checked my password, any idea what can be?

b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'
Traceback (most recent call last):File "/Users/myuser/Documents/migrations/untitled3.py", line 29, in read_email_from_gmailmail.login(FROM_EMAIL,FROM_PWD)File "/Users/myuser/opt/anaconda3/lib/python3.9/imaplib.py", line 612, in loginraise self.error(dat[-1])
imaplib.IMAP4.error: b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'

Here my code: Also i want to know which port I can use?

import smtplib
import time
import imaplib
import email
import traceback ORG_EMAIL = "@gmail.com" 
FROM_EMAIL = "myemail" + ORG_EMAIL

My main goal is be able to get the CSV file from each email, but for now I just want to read messages.

Best way to read email is using GMAIL API. Google has stopped accessing gmail account using username and password via any outside app from 30 the May 2022. So this is how you read gmail from python.

What this app does:

• Read gmail message (Unread)
• Make the message as Read after reading the message
