Slack SAML integration
Acceptto integrates with Slack via its SAML solution and provides a single sign-on (SSO) MFA to ensure the convenience of cloud SSO without its potential security risks. Multi-Factor Authentication (MFA) is an extra layer of security used when logging into websites or apps. Individuals are authenticated through more than one required security and validation procedure that only you know or have access to. SAML-based SSO gives members access to Slack through an Acceptto identity provider (IDP).
Prerequisites
An Acceptto account with a configured Identity Provider and LDAP Agent.
For more information, see the LDAP Agent deployment guide.
