One website I know uses postal mail to send a confirmation code.
This seems much more trustworthy to me than mobile phone numbers.
However I am curious to hear counterarguments, if there are any.

- 3xblah 8y agoI was careful to use the word "trustworthy". Are you saying that speed affects trustworthiness?
- xfitm3 8y agoSnail mail MFA only proves you have access to the mailbox. Phone numbers are typically personal, not shared. Addresses are typically shared.
- 3xblah 8y agoThat is a fair point. How would you counter the following? When a call is made or a text is sent to a mobile number is is not addressed to anyone in particular. It is addressed to the number only. Mobile phone "MFA" only proves someone has access to the SIM card. It could be anyone. When a letter is sent to a mailing address, it can be addressed to a particular person. In many countries, there are laws that protect postal mail from tampering.
