New user experience for consumer authentication

Robin.  All the hype is confusing.  Will we able to continue with our passwords?  Linux does not currently support all the extras.  And current passkey technology is proprietary, specific to an individual device and not durable across changes to device state.  Historical Microsoft customers included individual professional users who were not the property of large employers and institutions that have Microsoft Entra accounts.  I'm sure the wise elders at Microsoft have already taken this into account.  It would be useful to know what Microsoft's plans are for non proprietary customers going forward.
