> Are passwords/double authentication the only way to keep things private and secure these days That's always been the case. The main promise of biometric security was not "better security", but better convenience. The best argument for it would be that it makes average security better, in the sense that more people use it than not use anything at all or re-using passwords, but it's not the best way to secure your devices. Password manager + U2F token is the most secure way to lock your accounts.
