How do you manage multiple Office355 tenants?

[thecomputerguy]

Two cases for this.

Case 1) Resetting passwords or adding/removing users.

I find myself ALL DAY LONG opening incognito, logging into a tenant, performing 2FA, then navigating through the slow O365 admin platform. Then closing incognito, realizing I forgot something, then doing it over again. It's slow and tedious when I have access to 20+ tenants.

Case 2). Making universal changes.

Say there is a universal change I want to make to 7 or 8 if my tenants like adding a conditional access policy that I feel several tenants would benefit from. Is there a way to do this without having to through through the whole logging into a tenant, performing 2FA, then navigating through the slow O365 admin platform. Then closing incognito, realizing I forgot something, then doing it over again.

One thing I'd recommend is using Firefox and its Multi-Account Containers feature and create a container for each tenant, and not necessarily logging out any too quickly since I presume you have reasonable physical security for the computer you're using. Each container is its own virtual world, completely isolated from the others, and you can jump between them much like you can jump between workspaces in browsers that support them. But, unlike workspaces, they exist as though it were a separate instance of Firefox virtually, rather than the way all workspaces are still a part of a single browser session.

I do not know of any way to make multi-tenant changes in one fell swoop. I'd imagine the easiest way to do this would be using CLI for M365.

Introduction - Microsoft365DSC - Your Cloud Configuration

You could have your base in a versioned DSC module so that you could gradually rollout a config change by pumping the version for each tenant. Or you could have one big pipeline that starts rolling it out throughout the tenants, though I would be careful of coupling everything too closely.

Thanks for that. Looks like a great tool, is open source, and is led/overseen by Microsoft's own folks.

The fewer wheels that need to be reinvented, the better.

But...at the end of the day, for many day to day tasks, I still find it easiest and quickest to log into a tenant with the GA account we set up in each tenant, storing the TOTP code in our HUDU system.
