I use Thundedrbird for my email a/cs. Gmail and Hotmail, (also Orange emails but now finished. Thanks EE!!)) Recently for some reason logging onto my one gmail a/c brings up this message; Sending of password for user harry.xxxxxx@gmail.com did not succeed. Mail server pop.gmail.com responded: Web login required: https://support.google.com/mail/answer/78754 Clicking the OK button brings up the message to enter a new password. Done this. Still no joy. My other gmail a/c, (slightly different name.) works OK. Using Google email website I can log on to the harry.xxxxx a/c. To my kowledge I have not altered any settings etc. I would like to continue to have all my emails in one place (Thunderbird) so any help would be much appreciated. Thanks.
