I've been using the application specific password for several years. The last few weeks I need to constantly renew these passwords. I have one for my phone and one for a Thunderbird mail client on my pc. Today I've had to renew the one for Thunderbird 2 times already ?? It comes up at totally random times, sometimes after hours, sometimes after weeks/months. I sent 2 mails to help service, only got an answer mail once. They sent me a link, when I use it, I get some message I don't have access rights ? This is a terribly annoying problem.
