What it does
Authy is a two-factor authentication app with cloud-backup and multi-device features described by Twilio.
Authy's backup and multi-device support are useful to examine before a phone replacement rather than after access is lost. Its official site presents the app as a free way to add a second sign-in factor to supported accounts. Document how the Authy account itself is recovered and keep each service's recovery codes separately.
