If you want to sync your 2FA keys in the cloud, you may be better off with LastPass Authenticator: https://blog.lastpass.com/2017/05/announcing-cloud-backup-for-lastpass-authenticator-easier-multifactor-security-for-everyone.html/ https://blog.lastpass.com/2017/05/announcing-cloud-backup-fo... I would still say it's not recommend to backup those keys in the cloud, and I hope LastPass at least has the common sense not to keep those keys on the same server as the LastPass passwords. However, a middle ground may be backing up the keys before you change/reset your phone, and then disabling the feature (I'm not sure if they actually wipe or reset those keys every time you disable the backup feature, though, but I hope they do that).
