What to expect

• Workspace Owners must set up 2FA for themselves to keep their backup password secure. 
• Guests must set up 2FA if they are not required to use SSO. 
• On workspaces where SSO is optional, members can use SSO or their email address and password to sign in to Slack. These members will also be notified when workspace-wide 2FA is turned on.
• 2FA in Slack will be turned off when a member connects, or binds, their SSO account.
