No grandma, don’t use the unphishable one-click passkey setup that syncs across all your devices. Instead, install a third-party password manager (no, no, not the one built in to your device or browser), then another TOTP app on your phone. It’s slower and more susceptible to phishing, but uhhh, what if you’re among the one in a million people that has their Google or Apple account wrongly banned?
