What is the tbauth:// protocol?

I think that Outlook uses it to get passwords because I saw this error message recently:

enter image description here

I have never seen this tbauth protocol and am curious what it is. Googling doesn't help much - the top result is a link to https://windows10dll.nirsoft.net/tbauth_dll.html which is about a DLL that has "tbauth protocol handler" in its description.

What is it used for, is it used only by Outlook, is it a public API or something internal?

TBAuth is a Single Sign-On (SSO) protocol - note this reference in the Windows registry, pointing to the tbauth.dll you mention:

[HKEY_CLASSES_ROOTCLSID{14654CA6-5711-491D-B89A-58E571679951}]

@="Microsoft TBAuth Single-Sign On Protocol"



[HKEY_CLASSES_ROOTCLSID{14654CA6-5711-491D-B89A-58E571679951}InProcServer32]

@="C:\Windows\System32\tbauth.dll"

The TB stands for Token Broker - this Word document on Azure Active Directory mentions it on page 59:

Token Broker in Windows 10 is a new authentication framework that
improves upon the former Web Application Broker in Windows 8.x and
which is designed to provide Single Sign-On (SSO) for browser, modern
business applications, and services.
