Hi, sorry for the late reply. That is why in the screenshots you see the part with "account recovery options". Although there is the classical way with emails/sms, the other way would be to register an additional device for the account, for example by scanning a QR code, like in the screenshots.

Moreover, Google/Apple/Microsoft password's manager may sync your passkeys/credentials across your devices if enabled.

My understanding is that something in the TPM cannot be exported.
