Sign a profile in to each platform

Browser sign-ins, tokens, and app passwords each profile needs before it can post.

Sign a profile in to each platform

One section per platform. LinkedIn, X, and Reddit sign in by hand in your Chrome; Bluesky takes a handle and an app password; GitHub takes a token; Hacker News takes a username and password; Slack takes a captured session.

Do the mapping first (Map Blowhorn profiles to Chrome profiles): every browser sign-in below opens in the profile's mapped Chrome.

LinkedIn, X, Reddit

Each keeps a persistent browser session. Refresh it with profile auth. With the username and password in the profile's config.yaml (LI_USERNAME and LI_PASSWORD, X_USERNAME and X_PASSWORD, RDDT_USERNAME and RDDT_PASSWORD), the login is attempted for you; otherwise the browser opens and you sign in by hand.

blowhorn profile auth --platform linkedin --profile ada
blowhorn profile auth --platform x --profile ada
blowhorn profile auth --platform reddit --profile ada

With --headless the browser still opens as a background window and only the automated login is attempted; the manual fallback is skipped. A CAPTCHA or second-factor challenge always hands back to you: unattended runs never wait for a person.

Bluesky

Log in with a handle and an app password. The pair is stored only when Bluesky accepts it, so a refused credential is never saved.

blowhorn profile auth --platform bluesky --profile ada

In a terminal it asks for both (the stored handle is the default; a blank app password keeps the stored one). Supply them without a prompt with --handle and --app-password-stdin. Otherwise the stored pair is logged in with and nothing is written. Make the app password in your Bluesky account settings; your main password never goes here.

GitHub

Store a personal access token as the profile's GH_TOKEN. It lands in the profile's GitHub credential in the store, never in config.yaml:

blowhorn profile set ada GH_TOKEN=<token>

Then validate it without following or reacting to anything:

blowhorn profile status --profile ada --check-platform github

The check reports the login the token signs in as and its scopes. A classic token needs user:follow to follow and repo to react; a fine-grained token needs read and write on Followers to follow, and on Issues (and Pull requests for PR targets) to react.

Hacker News

Store the login with profile set. Both keys are needed; the password is read from the store and never from config.yaml:

blowhorn profile set ada HN_USERNAME=<account> HN_PASSWORD=<password>

Check it landed, with the password shown only as set or not set:

blowhorn profile get ada

Slack

Capture your signed-in web session into the profile's Slack credential in the store:

blowhorn profile auth --platform slack --profile ada

A browser window opens; sign in to Slack, and the session is extracted. No Slack app install is needed. To capture a new workspace, name it:

blowhorn profile auth --platform slack --profile ada --workspace acme.slack.com

Omit --workspace to refresh every workspace already listed under slack_workspaces in that credential.
