If you use #Authy for 2-factor authentication, please be aware that since March 19th (I might be off for a couple days though) the desktop apps will be discontinued. So basically they force you to use mobile apps or nothing. I don't know about you, but for me it's totally unacceptable behavior. I tried the desktop app and didn't like it (because it's basically a web version wrapped in an executable), but I know people who use them namely because they have a desktop app. If I were you, I would migrate to something else just because it's not how good business is done.
Support article about it on their website: support.authy.com/hc/articles/… (thanks @twynn for the link!)
