The typical U2F user carries at least two keys. (one on their person and one stored securely for backup) I hope they decide to change this because it will cause a ton of customer support problems in their future.</text><parent_chain></parent_chain></comment><story><title>AWS now supports U2F/Yubikeys</title><url>https://aws.amazon.com/blogs/security/use-yubikey-security-key-sign-into-aws-management-console/</url></story>

Docs are unclear as to what the fallback 2FA is, if there is one. Also, as before, you can only have one 2FA method configured at a time, so say goodbye to your hardware tokens or TOTP configurations for AWS if you switch to U2F.&lt;p&gt;EDIT: &amp;quot;Fallback&amp;quot; is to have root account remove your IAM user 2FA. If root account 2FA is lost they have a few alternative verification options like email or phone call.
