How can an invited Teams guest regain the QR code for Microsoft Authenticator?
Do you still have the QR code? Press + on the authenticator app on the top right to add and rescan the QR code previously send - it should re-add the account to Authenticator.
If you cannot find the QR code or have deleted it, get the administrator in Azure AD to resend the guest invite to you, or barring this, hard delete you from Azure AD and then re-add you, that should restart the process.
Hope that answers your question
Best, Chris
Actually, even as guest, one can go to the "security info" page (which really is the "mfa" page: shortcut: aka.ms/mfasetup), change the org in the upper right corner (the org symbol), add another authenticator
Someone put a great description out there, thanks a lot for that! Just linking it here as well: https://office365itpros.com/2023/01/04/microsoft-authenticator-app-qr/
