I've been in the market for an open source authenticator that works on android and desktop with a cloud sync. I cannot find one and so I'm stuck on using authy. I have exported all my TOTP tokens in hopes that one might turn up. Aegis, like andOTP and others, does not appear to have a desktop client.
