Good to Go
Edit: Because of the developer’s response, I am changing my review from 4 stars to 5. This app has everything I am looking for- It is FOSS, it has a great user interface, you can import, export, cloud sync your seeds, and backup offline. You can also sort your seeds alphabetically or manually, which serves the same purpose as a “favorite” button. The fact that it is open source is a HUGE plus. Hopefully this app sticks around for a while and remains FOSS for the duration. If you need cross-platform non-mobile support, there is a browser extension too.
I’m searching for a Raivo replacement. 2fas is pretty good. It has a nice user interface and is intuitive to use. It doesn't have a lot of extras that would cause it to be less user friendly. I would suggest it with a slight caveat. One thing I like about Raivo is the way it uses standard zip files for its backup export. In that folder it creates to files; a json and a html. So, I can unzip the export on my computer and print either one for a paper backup I put in my safe. 2fas uses a .2fas file extension in its export. This means there isn’t a quick way change 2fa apps unless your next app choice has the ability to import a 2fas backup. Which by the way 2fas can import and/or gives instructions how to import from Google, Raivo, etc. which is pretty nice.
Developer Response ,
Thanks for the feedback, but there is a slight misunderstanding. The .2fas file our app generates is a .json file, therefore all the apps that support the .json files will be able to import our file without a problem. 😁
