#Multi-Factor-Authentication2 discussing

Hey all, 

We are running into issues accessing the mobile app since MFA has been enforced for privileged users. 

1. If a user sets up the Built-in Authentication on desktop, they are not able to login to mobile. Our company only allows Windows Hello authentication on desktop, and users are unable to "Verify Identity" in iOS when this is added on desktop. The screen is frozen on this even when using "Login for Admin."
2. We have gone into Salesforce Classic on the mobile browser and added a passkey, but it doesn't work in the app. 
3. If we delete the Built-in Authenticator on desktop and add a passkey for mobile, it then requires users to have their phones to login on desktop. 

None of these scenarios are ideal, and I'm wondering if anyone has been able to use Window Hello to authenticate desktop and then directly login on mobile with the their Face ID, Touch ID, or passcode? We have found hacky ways to get people logged in with generating a temporary code then having them setup a passkey etc, but it seems like the app should automatically guide users to setup a mobile passkey even when there's an authenticator for desktop? Is this a bug with MFA and mobile because it doesn't seem like this should be expected behavior? 

Been on hold for hours for support - Still holding, day 5+, tried to use the agent but it cut me off, cases can't be created.  In the meantime, anyone know how to resolve this as I wait......to create a case, or talk to someone.  

 I am the sole System Administrator for our Salesforce organization and have become locked out of my account after accidentally deleting the only registered Windows Hello passkey during testing. While my username and password are still valid, Salesforce requires MFA and no longer recognizes any authentication method, leaving me unable to access the organization or reset my own MFA settings. I have already attempted all available recovery options, including "Having Trouble?", checking Chrome and Windows for saved passkeys, and trying multiple devices and browsers, without success. As there are no other administrators in the organization, I am requesting assistance resetting my MFA registration, removing the deleted passkey, issuing a temporary verification code, or otherwise allowing me to register a new authentication method after verifying my identity and ownership of the organization.
