I was using Raivo but today I learned that they stopped developing it. I'm looking for an alternative, does anyone have a good suggestion like Raivo?
If I am not wrong Authy is available on IOS platform too and it's considered as best compared to any other platform with the knowledge I have so definitely you can take a look at it if your looking for an alternative.
2FAS is another open-source authenticator which can also be added in your list.
