Per Talk Help,
We’re winding down Google Talk. On June 16, 2022, we’ll end our support for third-party apps, including Pidgin and Gajim, as we announced in 2017.
To continue to chat with your contacts, we recommend using Google Chat. You can more easily plan with others, share and collaborate on files, and assign tasks with Chat’s enhanced Spaces feature. You also have the same strong phishing protections we build in Gmail and accessibility features like screen reader support.
If you try to sign in to Google Talk on or after June 16, 2022, you’ll get a sign in error.
