I'd give a key to my bank that they could create signatures with if I asked for (and was authenticated with) that third parties could trust to bypass my passkey. I'd pay a fee for it, the bank holds liability for verifying my identity. Banks aren't perfect but mine already has all my money and the deed to my house. I trust the safety of my bank more than I trust Google not to lock me out or all my hardware to be destroyed.
