Lastpass recently (march 2016) released a new app called lastpass authenticator. Reading their blog post and the description of the app features, it looks like to me that the app does nothing more than TOTP.
Now the algorithm for TOTP is well documented: on linux you can roll your own implementation or use a ready made solution in a shell script, and on android you have choices such as google authenticator or the excellent FreeOTP (and maybe others).
My question is then what is the added value of lastpass authenticator? Why should I use their app instead of FreeOTP, which is opensource and does exactly the same job?
They already supported google authenticator, so I do not believe that they would go through the trouble of building and releasing another app, while there are already other good implementations that do exactly the same thing. There are problably extra security features, or major usability improvement that I missed.
What did I miss? Or is there no actual improvement offered by the app?
