# Revoking a Claude Code OAuth token
|
||
|
||
Research into how to revoke a long-lived `CLAUDE_CODE_OAUTH_TOKEN` (the kind
|
||
`claude setup-token` mints), prompted by needing to rotate a token baked into a
|
||
bot-bottle container.
|
||
|
||
## Summary
|
||
|
||
There is a documented revoke button, but it does not currently provide reliable
|
||
immediate invalidation. As of early 2026, an open bug shows tokens remaining
|
||
valid for **3–4 days after explicit revocation**, including after "Log out all
|
||
sessions". Anthropic has not commented on the bug or on the related
|
||
feature-request issue. For a known-leaked token there is no guaranteed way to
|
||
make it stop working today; rotate immediately and hope server-side enforcement
|
||
catches up.
|
||
|
||
## What works (with caveats)
|
||
|
||
`claude.ai/settings/claude-code` lists active Claude Code instances with a
|
||
per-entry "Revoke" control. This is the only path mentioned in any GitHub
|
||
issue thread; it is not mentioned in the
|
||
[official auth docs](https://code.claude.com/docs/en/authentication), which
|
||
document `claude setup-token` but say nothing about revocation.
|
||
|
||
A second lever is `claude.ai → Settings → Account → Active Sessions → "Log
|
||
out all sessions"`.
|
||
|
||
Empirically, neither reliably propagates. [Issue #43801](https://github.com/anthropics/claude-code/issues/43801)
|
||
documents a reproducible failure: the reporter shut down their VM completely
|
||
while offline, performed both revocation actions via claude.ai, waited 3–4
|
||
days, then booted the VM cold — Claude Code authenticated without re-login.
|
||
Because the VM was offline during the revocation window, this isolates the
|
||
failure to the server side. The issue is open with zero Anthropic staff
|
||
responses.
|
||
|
||
[Issue #34198](https://github.com/anthropics/claude-code/issues/34198) (filed
|
||
March 2026) requests proper server-side revocation on `claude logout` and
|
||
devcontainer shutdown. Also open, also no Anthropic response.
|
||
|
||
## What does not work
|
||
|
||
`claude logout` (or `claude /logout`) only clears local credentials. It makes
|
||
no server-side revocation call. Do not rely on it.
|
||
|
||
It is also not confirmed whether changing the Anthropic account password or
|
||
revoking the broader account session invalidates Claude Code OAuth tokens; no
|
||
issue thread tested this directly.
|
||
|
||
## Unconfirmed
|
||
|
||
- Whether `setup-token`-generated long-lived tokens appear on
|
||
`claude.ai/settings/claude-code` as a distinct entry type vs. interactive
|
||
sessions. Plausible but not confirmed.
|
||
- Whether the 3–4 day server-enforcement gap is consistent or has been
|
||
silently reduced since the issue was filed. No release notes mention it.
|
||
- Whether contacting Anthropic support for a leaked token gets faster
|
||
server-side action than the self-service UI.
|
||
|
||
## Practical rotation procedure
|
||
|
||
For a known-leaked or suspected-leaked token:
|
||
|
||
1. Revoke the entry at `claude.ai/settings/claude-code`.
|
||
2. Run "Log out all sessions" under Settings → Account → Active Sessions.
|
||
3. Run `claude setup-token` to mint a replacement, and rotate it into
|
||
`BOT_BOTTLE_CLAUDE_OAUTH_TOKEN` immediately.
|
||
4. Email Anthropic support at `support.anthropic.com`. Security issues
|
||
sometimes get attention that GitHub issues do not.
|
||
|
||
The new token is in effect right away; the old token may continue to
|
||
authenticate for up to several days. There is no client-side mitigation for
|
||
that — the server is the only authority.
