Quick answer
Yes, Microsoft 365 accounts should use two-step login where possible, especially owners, admin users and staff who handle invoices, customer records or passwords.
Plain-English explanation
This guide keeps the business problem first, then shows how it relates to the Essential Eight. It is a practical support guide, not a formal certification, audit, legal advice or insurance advice.
Your business uses Outlook, Teams, OneDrive or SharePoint. Staff worry two-step login will slow them down or lock them out, but email is one of the highest-value targets.
Business owner scenario
Your business uses Outlook, Teams, OneDrive or SharePoint. Staff worry two-step login will slow them down or lock them out, but email is one of the highest-value targets.
What can go wrong
A stolen password may be enough to access email if two-step login is not active.
Admin accounts without extra protection can expose many users at once.
Shared mailboxes and old accounts can be overlooked.
A rushed rollout can lock out staff if backup methods are not planned.
What to do now
Start with owner and admin accounts.
Plan staff rollout and backup sign-in methods.
Check shared mailboxes, old users and contractor accounts.
Make sure recovery details are current.
What not to do
Do not turn on two-step login without a rollout plan.
Do not leave the main admin account protected only by a password.
Do not ignore accounts used for accounting, websites or social media.
