Slack TOTP


To improve security while accessing Slack™, users should utilize Multi-Factor Authentication. Multi-Factor Authentication adds an extra layer around the traditional username and password login, thus preventing unwanted access by threat actors to your Slack instance. With Acceptto™ Multi-Factor Authentication adding that extra layer is simple and cost-effective.

This guide walks you through the following steps:

  1. Configure the Slack instance to use Multi-Factor Authentication
  2. Scan a QR code generated by Slack with the Acceptto Mobile Application.
  3. Log in to Slack using Multi-Factor Authentication.
