Enter Credentials
I've been using TB for a long time. No problems. About a week ago it asked me to enter credentials. When I tried to enter it went into a loop.See below. In GMail I've allowed less secure Apps and set 2 factor authentication. I've provided screen prints of relevant data and Google settings. The problem occurs with all PCs running windows 10 but not with Windows 7 or with Android. Any ideas? Many thanks

I've solved the problem myself.
When there was a GMail outage the GMAIL passwords became corrupted.
I therefore deleted all Thunderbird passwords and I was then prompted for the passwords again.
On re-entry, the problem was solved.
Took some time to sort this out.
Hope this helps someone else.
