Authentication

0. Open a private chat with the bridge bot. Usually @slackbot:your.server.
   • If the bot doesn't accept the invite, see the troubleshooting page

Password login

Password login supports all Slack features, except portals for Slack conversations will not be created immediately after login. If your Slack account does not have a password you need to use token login or add a password to your account.

1. Send the command login-password <email address> <slack team domain> <password>, for example login-password me@email.com workplacechat.slack.com hunter2.

Password login isn't guaranteed to always be fully supported, but you can switch to token-based login at any time afterwards by following the instructions in the Token login section without signing out.

Token login

Token login works for any Slack account and fully supports all Slack features.

1. Login to the Slack web app in a browser, and acquire the authentication token and d cookie from inside the app.
   • The token starts with xoxc- and can be found using the browser devtools, in the app's local storage inside the localConfig_v2 object, as teams['your team ID'].token.
   • The cookie is named d, it starts with xoxd- and can be found in the cookies section in the devtools.
2. Send the command login-token <token> <cookie>, for example login-token xoxc-tokengoeshere xoxd-cookiegoeshere

After login using a token, all your joined channels will automatically be bridged into Matrix, but DMs will only appear once you receive messages in them.
