The simplicity of the app and its availability on almost all the major platforms unlink many of its competiters (e.g., Google Authenticator) is the main reason I use it.
Also, sync speed between different platforms is super fast and it is password protected. Also, we can control all devices from a single device which can be useful if one of our device gets lost. Review collected by and hosted on G2.com.
I would like to see more documentation on how our things are private and safe with authy because it is not an open source app. Maybe they should release a white paper telling us their methodology behind their backend. Review collected by and hosted on G2.com.
