Keystone

Keystone is a simple Slack application for generating TOTP codes for a shared account.

Usage

Just type /keystone in the configured channel to be granted a new two-factor code:

Configuration

Keystone runs as a self-hosted Slack Bolt application.

The bot is configured via environment variables. You can use .env.example as a template.

1. Create a new Slack application and install it into your workspace.
2. Get the bot token from the "OAuth & Permissions" page & store it as SLACK_BOT_TOKEN.
3. Get the signing secret from the "App Credentials" page & store it as SLACK_SIGNING_SECRET.
4. Store your TOTP secret in the TOTP_SECRET environment variable. It looks like otpauth://totp/... and can be read via 1Password (and perhaps other tools). This is how we'll generate two-factor codes for this website.
5. Create a /keystone command on the "Slash Commands" tab. The Request URL should point to your app, with a /slack/events path. For example, if you're hosting your Keystone bot at https://keystone-bot.herokuapp.com/, you'd enter https://keystone-bot.herokuapp.com/slack/events here.
6. Optionally, set KEYSTONE_CHANNEL to limit Keystone usage to a specific channel.

Roadmap

At some point, I'd like to add support for multiple TOTP generators & easier secret configuration.
