In the case of Schwab it's only with their app. If I wanted a geolocation leash up my ass I wouldn't be complaining about this: if they don't trust me as a customer then screw them, I'll find a bank who does. Schwab's notion of non-SMS 2FA is their app. I want to use my laptop on a VPN using a FIDO key or TOTP and Schwab doesn't support this.
