Acces to external user without single-use code
Hi, there are some differences in behavior depending on what sharing feature you're using, the org. configuration and what accounts your externals are on. I recommend you verify the OTP (email one-time passcode in Azure AD) and enable the AAD B2B integration with OneDrive and SharePoint. Usually the code is used when the above is not enabled and the externals are not having password-backed accounts.
This is the "old" way using secure external SharePoint sharing
