My G-Mail account does not accept username & password from POP3 account

Recently I came into a situation that when a client changed his gmail password from web mail he could access web mail with the new password but his password was rejected from POP3 enabled clients like MS Outlook.The solution I found is:

1. Login to your gmail web mail.

2. Click this link & press continue.

That’s it! Now your pop3 account should be unblocked…
