What
When you sign in with a claude.ai account, Claude Code stores sign-in tokens (the saved credentials that keep you logged in) under the name claudeAiOauth. Before saving them, it now builds a value tied to the current host, the server address Claude Code is talking to.
Why
In practice, saved sign-in details are now linked to a specific host rather than stored with no record of where they came from.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say how the recorded host is used afterwards.
