Also. Whatever app you use, when you set up OTP don't forget to save screenshots of your original qr codes, in a veracrypt container ideally. Don't rely (only) on other people's work and will for such sensitive and personal data.
Couldn't be happier with Raivo OTP on iPhone. Unfortunately it's iOS only but as far as I know it's 100% work of passion and bullshit free app maintained by a single user. Allows to export your entries in a very nice way... which is very securing regarding the kind of data entrusted. No risk of being locked out. Thanks @tijme!
On MacOS, using Maestral.app made my Dropbox experience a lot better. Well, it's still dropbox behind, but the app itself is way lighter and nicer to use.
My trust in them had been broken as soon as they asked me to honour a bill when my vpn subscription ended, instead of notifying me to renew. Respectable companies don't use such asshole design/wording. They're a fraud.
