Not OP, but I escaped Authy over a year ago and I've been happy with 2FAS on Android. Aegis is also very good. 2FAS has backup to Google Drive. Aegis does Android Cloud Backup. Aegis is available on FDroid. IIRC I chose 2FAS for purely aesthetic reasons, but I could've easily gone with Aegis and been happy too.
Speaking of escaping Authy, good luck with that. I had to use their desktop app and api to pull my data. I read in another comment that they've recently closed that api. So, you might be stuck migrating each account manually. That bullshit alone is worth the trouble of moving.
Yep, exactly this. I, purely coincidentally, did this procedure of hacking up their desktop client to export my tokens 3 weeks before they turned off the API the desktop client uses. "by the skin of my teeth" as it were.
