About Legacy authentication labs
How many Legacy authentication labs are there?
There is 1 Legacy authentication lab on Identity Bytes Labs, taking about 1 hours in total.
Where should I start with Legacy authentication?
Start with "Block Legacy Authentication with Conditional Access". Find who still uses legacy authentication in Entra ID, then block it safely with a report-only Conditional Access policy before you enforce it.
Do I need a production tenant?
No. Every lab is designed for a free, disposable Microsoft Entra test tenant. Never run lab steps against an environment people depend on.
