Volunteer Management runs in your browser but relies on the RfR Volunteers Slack to know who you are. There are two options for logging in:

App (recommended): Uses your Slack App (mobile or desktop). After it opens, click the "Volunteer Management Login" button and follow the instructions.

Browser: Uses your browser's Slack session. You'll be directed to login to Slack in your browser if you aren't already.

If you mainly use Slack via app, the app button should be quickest since you won't have to login to Slack itself again.
