Nothing changed on my end, Pro subscription still active, but Xcode 26.5 (17F42) simply does not want to log into Codex anymore. It opens the OAuth flow and after finishing and closing the window, it still says "Not Signed In".
Codex login works everywhere else, including the Codex app.
What to do?
@JustinInSeattle Thanks, I got your report in my list, the team will communicate using that platform when they have a resolution in place. Again, appreciate your time and patience.

Okay, I've tested with both Codex and Claude, neither of them work despite both saying (in Safari) that connection successful, and you can close the window.
