Using Temporary Access Pass (TAP) with members

Note: TAP only works with members and a passwordless authentication once setup

https://aka.ms/mysecurityinfo

Creating Microsoft Entra ID member users

Users are created on the tenant with a known or registered domain. The member user can use a TAP to onboard or a password.

When using TAP, no password is returned and the user must register a FIDO2 key, etc.

Creating Microsoft Entra ID guest users

And email with a domain unknown or not registered on the tenant will be created using an invite.

TAP cannot be used for guests.

Note for live or Microsoft accounts the security info is at:
