Walkthrough

The wiki now documents how to create a Tailscale API token, choose a non-expiring OAuth credential, and store the token as TS_API_TOKEN in the secrets file.

Changes: Tailscale API token documentation

Layer / File(s) Summary
Document token setup
wiki/TAILSCALE_API_TOKEN.md
The guide explains how to generate a token with a maximum 90-day lifetime, use an OAuth client with auth_keys, dns, and devices scopes for a non-expiring credential, and store TS_API_TOKEN in the secrets file. It warns against sharing the token in chat or issues.

Merge Risk: Moderate · previous review e2a2c

The new wiki guide fails the repository's Markdown lint check. Readers who follow its OAuth or secrets-file instructions may end up with credentials the host scripts cannot use, or with a token file that is readable by other local users. Fix the lint errors and complete these steps before merging.

- Line 8: Update the token setup instructions near the secrets-file guidance to
clarify that entering the token is not a one-time task. Tell readers to replace
TS_API_TOKEN when the current API token expires or is revoked, while preserving
the existing secret-handling guidance.
- Line 11: Update the token-editing instructions around the `nano` command to
ensure `~/.config/born2root/b2b-secrets` exists with mode 600 or 400 before
readers enter the token. Preserve the existing guidance to edit the file in
`nano`, and do not rely on `nano` to create it securely.
- Line 11: Update the Tailscale API token instructions to tell readers to edit
the secrets file selected by B2B_SECRETS, the active profile, or an existing
repository-root .b2b-secrets; identify ~/.config/born2root/b2b-secrets as the
default path.
- Line 6: Update the OAuth client guidance to explain that OAuth-created auth
keys must use tags the client is permitted to apply. Note that ts_mint_authkey
requests tag:b2b by default, and explain how to grant the OAuth client ownership
of that tag or set TS_TAGS to a permitted tag.
- Line 6: Update the credential instructions around TS_API_TOKEN to document
configuring the OAuth client and storing both TS_OAUTH_CLIENT_ID and
TS_OAUTH_CLIENT_SECRET. Explain that ts_api_token prefers a nonempty API token,
so readers switching to OAuth must clear TS_API_TOKEN.
- Line 6: Update the OAuth client scope guidance in the credential instructions
to use the current `devices:core` scope with write access instead of the legacy
`devices` scope; preserve the existing `auth_keys` and `dns` scopes.
- Line 3: Update the Tailscale API token documentation to wrap bare URLs in
Markdown link syntax, reflow the long lines without changing their meaning, and
add the appropriate language identifier to the code fence based on its contents.

Document the required OAuth tags.

OAuth-created auth keys must use permitted tags. ts_mint_authkey requests tag:b2b by default, so a client without permission for that tag cannot mint the key. Explain how to configure tag ownership or set TS_TAGS to a permitted tag. (tailscale.com)

Document how to configure the OAuth client.

The remaining instructions only populate TS_API_TOKEN. ts_api_token instead requires both TS_OAUTH_CLIENT_ID and TS_OAUTH_CLIENT_SECRET for OAuth, and prefers a nonempty API token. Tell readers to store both OAuth values and clear TS_API_TOKEN when switching. (raw.githubusercontent.com)

Use the current device scope.

New OAuth clients use devices:core, not the legacy devices scope. Select write access so the script can disable device key expiry.

Secure the file before entering the token.

If the file does not exist, nano can create it with permissions derived from the umask. With a permissive umask and searchable parent directories, other local users can read the token. secret_get also rejects modes other than 600 or 400. Instruct readers to create or secure the file before editing it. (raw.githubusercontent.com)

Use the selected secrets-file path.

If B2B_SECRETS, the profile, or an existing repository-root .b2b-secrets selects another file, the scripts do not read the token added to the default file. API operations can then fail or fall back to manual steps.

Tell readers to edit the selected secrets file. Identify the shown path as the default.
