I've just moved from a different Authenticator app TO this Proton Authenticator app, and much prefer this Proton app... Keep up the good work, Proton!

Best Authenticator Period. Thanks to Proton for not limiting the Free version. One issue- Sync with Windows and Android is a bit slow. It doesn't show the new codes immediately it takes 1-2 mins. I hope it will be fixed soon ❤️.
