Authentification failed for Google Talk

Hi, new installation of Jitsi on Windows 10.
I try to connect to Google Talk using my regular Gmail e-mail and password.
But I get:
“Authentification failed for xxx@gmail.com (Google Talk). The password you entered is not valid.”
Two-factor authentification is disabled and using @googlemail.com doesn’t help either. And I’ve tried this with different Gmail addresses.
What can I do, please?

talk to google obvious?

Pardon?

I’ve found the solution myself.
Google is blocking the login from the Jitsi software. Probably I wasn’t the only one with this problem.
I’ve then set up a free account with jabber.de and it’s working fine now.
