Hi,
Thanks for reaching out to Microsoft Q&A.
==>I tought maybe it's because we have that policy :
Interactive logon:Do not display last user name
Per my experience, you are right. Please refer to the official article. The potential impact of the policy:
Users must always type their usernames and passwords when they log on locally or to the domain. The sign in tiles of all logged on users aren't displayed. When this policy is enabled, you will be unable to change the default credential provider to anything other than username/password. In addition, this policy may be incompatible with autologon and multi-factor unlock.
Interactive logon: Don't display username at sign-in
Interactive logon: Don't display last signed-in
Thanks for your time. Have a nice day!
Best regards,
Simon
